Be sure to filter people's opinions by their gear list.
Somebody may say "I love my XXX recorder," which
is cool, but then you see that they are using it as a
back end to a $1500 preamp and $3000 worth of mics.
Do you have to keep the recorder small, or are you
willing to consider a full size recorder? For $600,
(or $450 occasionally on eBay) you can buy the
Fostex FR-2LE, which is miles better than any pocket
size recorder. Of course, you'll need external mics,
cables, mic stands, duct tape, and a big bag to carry
it all in.
let's assume you're trying to stay pocket-size.
Will you be stealth recording, or taping in the open?
Will you use the built-in mics or externals?
Are you taping just for your personal interest, or do the
artists expect your recordings to be the basis for demo tapes
or commercial CDs?
