I've had a few accordions over the years. They're NOT as cheap as some people might think. For example one I'd love to get my hands on is a hohner gola. 2nd hand they often cost £15,000 + $20,000 ? ) My first full midi accordion I bought was around 28 years ago THAT was about £3,000, then on top of that, a roland MT32 expander about £100 or so. ( Wonder how many folks on here used one of these babys ? ) Not bumming here but I think I was one of the first in my area to have a midi accordion.
I've also owned a hohner morino IV musette accordion ( my favourite and I want it back LOL ) Excelsior multi musette ( hated it ), crucianelli 35 pns, crucianelli magicvox, elkavoxF3, elkavox'83 and my present one, an excelsior 940. Also Had various expanders. Between those, amplification, must be over £20k
