I have to second Bruce.
John Roger is a fine wood craftsman.
I spent some time talking with him and trying his accordions many years ago at an accordion festival.
The accordions that I tried at that time were build on an old traditional design and were a bit more mellow in sound and volume than say a Martin or Bon Tee which are brighter and louder.
As I say, this was 15 years ago, so I know nothing about his current designs.
Regardless they were fine, very playable instruments with very attractive, quality wood working.
If I didn't already have too many accordions, I would consider buying it myself.
hey guys, I bought an accordion today....found it on CraigsList in Houston....it's a walnut, model 2 Acadian that was made by Marc, pitched in C....Bought it from a young man who bought it new in August of last year but hasn't had time to play it. Got a Peavey gig bag, shoulder strap and Marc's instructional DVD in the deal....I'm a student musician again !
