What should I buy for a music practice looper

[Stewart Dean <sdean@bard.edu>]

OK, all I want is the ability to have a melody replayed in an endless
loop so I can practice backup against it.  I'm NOT using to make or
build up loops....JUST to practice against.  I need a loop something
like 2-4 minutes long.  What should I buy?

I'm looking at a BOSS SP-202; would that fill the bill?  Any ideas where
I could find one used?  Will the BR-8 do loops?
Suggestions?
