Hi Dan,
You pose an interesting but difficult to answer question. Eddy has provided you with a really good example of the dangers associated with someone attempting to be the best by buying the best, and the same is as true with accordions as it is with fishing tackle.
To expand slightly on Eddy's fine example, I will provide another example. Every Monday night, I would shoot at the Police Range. One of the pistols I owned was a model 28 Smith & Wesson .357 Magnum, with which I consistently ripped the middle out of targets. One of my contemporaries owned a handmade French pistol of the same calibre, but costing over four times as much as my pistol. He imagined that buying the best would make him the best, but there was one serious flaw in his logic ................ he couldn't hit a cow's a**e with a banjo.
Having put that picture in your head, I will now turn to accordions. A friend of mine plays a Bugari on stage, and I love the sound it makes. Whether or not it would make the same sweet music in my hands is debatable, but I think I know the answer. I have played the Bugari on a few occasions, and it certainly is a lovely instrument. Would I want to buy one? Certainly not !
Kind Regards,
Stephen.
