Don't feel alone. Many of us have various instruments, it's just part of being a muscian or being musical minded.

I have a clarinet, tenor sax, piano, autoharp, dobro, upright English type bass, acoustic-electric bass, mandolin and 3 banjos. That's not being greedy, just someone who wants to try different instruments and see how they play and sound.

Oh, and I forgot, 2 Martin guitars. 

I guess no one told you when you got into all this, but banjos are agents of mind control. They are herd animals that NEED company and they will project "banjo aquisition thoughts" into your brain until you give up. You can either surrender now or later but surender you must – not "if," only "when." banjered

banjered speaks the sad, but undeniable truth!

I’d only add — don’t be afraid to buy used, provided you can do so safely on a platform like Reverb or a trusted seller here. You’ll take less of a hit if you decide it’s not a good fit for you and resell… and frankly, a banjo you buy from a player has a better chance of arriving with a proper setup, dialed in by the previous owner. Of course same applies to specialty banjo shops, I’d imagine…

Lastly, modern banjos are surprisingly durable instruments. You’d have to be pretty ruthless to damage one beyond playability — aside from dropping it or knocking it off a stand. So I wouldn’t be too afraid of something that shows a little wear, in terms of aesthetics or fret wear…  most issues can be fixed with a bit of tweaking.

Just take your time. The AC-1 is a great instrument to start on, and a good one to keep for trips or as a couch banjo. Listen a lot to different players and try to figure out what you like about their tone. I'm not suggesting buying a Capek because you like Ned Luberecki, a Nechville because you like Billy Failing, or a Gibson because you like a Gibson player. But just get a sense of the tone, dryness/sustain, etc. that you like. Play everything you can get your hands on because you'll start to understand that what speaks to you is more complicated than tone. I cannot explain it, but the instruments I gravitate to are not the most expensive ones. I bought a Clawgrass 2. It was every bit as good as you could expect, and the tone was excellent. For reasons I cannot explain, it just was not the one I would pick up when I wanted to play. I also have a really good Flatiron mandolin and one of the Eastman MD305, which is sort of the standard-issue starter to intermediate mandolin. The Flatiron sounds better, but I like playing the Eastman more. My favorite resonator was built by someone who is no longer well known. If you are on FB, follow Jim Britton of Ceres Banjos. He posts at least one video every few days, often playing the same or similar licks/songs. If you study those enough you will begin to pick out distinctions between instruments. The other good news for you is that there probably hasn't been a better time to buy used, and it may get even better from the buyer side. You can get some used K-35 (maple) or RK-36 for around $800. Most of these are fantastic banjos that you could proudly play anywhere. Also, search the members here for folks in your area. And keep an eye on FB marketplace. The Hangout is the best place to see what good stuff is coming available, but the best deals are often on FB Marketplace if you know what you are looking for. Gold Tone also has warehouse sales of "blems" for ridiculous prices at times. Their new models are also great. I'm interested in the new 100 with a tone hoop because I am going more for lighter banjos these days. Looks like a lot of banjo for $1K.

Why???
Maybe you like the hell out of playing the banjo and want a little advantage to help. Having a nicer instrument certainly doesn’t hurt, and does make playing a little easier. In other words………You’re Screwed……..just go buy it!!!
Slammer!!!

Just keep playing. Don't become a gearhead. The dopamine shot of a new toy will wear off and two weeks later you'll want another one. 

You've been playing for a couple weeks so a bit of the shine is wearing off and you're getting to the point where you need to really practice your rudimentary skills. Practicing skills is not the most fun thing and it doesn't give you that instant dopamine hit that buying another banjo will give you. But buying a new instrument won't make you better. Buying a different type of banjo will only distract you from practicing actual skills. And if you want the real satisfying feeling, that actually lasts more than a day, you need to develop those skills. 

You have a banjo. You like your banjo. Just play your banjo.

The best player I personally know has owned 2 banjos. He started on Goodtime, and then upgraded to a Prucha. He never talks about new banjos. He just plays, a lot. That's how you get good.

Also stay away from this website hecause every second you spend here is a second spent not playing banjo and nothing you do here will improve your banjo skills. 

If you want us to talk you out of buying more banjos you've come to the wrong place.
