Hi, I play a 12 button bass kids sized piano accordion. It's comfy, and sounds okay too. The big score, for me, would be a kids size 24 button bass, with voicing keys on the piano side. The big Chrysler sized ones are easy to find but brutal to gig with if you aren't sitting down the whole time. They do tend to have better tone though. Pricewise, you can find unbelievable deals at garage sales. Pawnshops are tending to price them high, now that more people are using them, and looking for good used ones Buying advice would be, for a starter, check the bellows. Make sure they aren't leaking air. Check all the keys to make sure they aren't horribly out of pitch, and that they sound the same pushing as pulling. Check the straps to see if they'll hold up. Here's another accordion/banjo joke. The definition of perfect pitch is heaving your banjo into a garbage dump, and hitting an accordion on the way in. Ciaou. Owl.
