All Bender stuff is first class, quality kit. I can only but
wish I owned an
1100 ST. It's probably the best (for bench use, that is), with lots of nice accessories available.
Are you thinking of getting one?

Given a free choice, not to mention a fat pocket book (or
wallet), I would probably go for the
800 ST, on the grounds of portability, interfacing possibilities, and "do anything" (all the standards) capability.
