(And "Why bother?" and "Isn't too much corn bad for your hips?" has already been flung, wiseguys!)

Our keyboard player has finally come to agree that we indeed need an accordion for several of our songs. We'd lure someone on board for this, as we've got plenty of prep work just w/ piano and organ as it is. But such players are mighty hard to find around here. He's eager to learn it.

So anyone got a good brand & model, at a good-enough price (let's say mid-level), to suggest? Buying used would be fine, if not preferable. The accordion equivalent of a good Squier.

Thanks!
