The ME-80 was launched ten years ago; that's quite a while in these circles. We have the bass version; it's very good, for its generation. The GP200 (and its sister versions...) is very much more modern. In ten years time it will doubtless be less attractive, but as of today, it has a fine reputation, and most functions required by most players. Try it anyway, and, if you're buying through t'web, send it back if you are not convinced of its qualities. Just my tuppence-worth.
