I'm curious, as sometimes in the future I'll want my own instrument. So I'm getting off to a head start on the subject. Plus "I'm on top" was asking about buying a flugel, but can't afford a really good one - so I wondered if a 2nd hand instrument would work for her. Obviously they are much cheaper, so you can get something much better for the same money. But what are the pitfalls, and is it a good idea?
