looping device for vocals?

[MrBERWELL@aol.com]

A friend of mine has been asking for recommendations on a device for 
creating
vocal loops.  I've been eyeing the Boomerang, but wonder how it actually
sounds with a vocal going through it.  I think this one does have a mic 
preamp
on it though.  If anyone has any suggestions on any device, please let me
know.  This would be primarily used in live settings, and it would need to 
be
foot controllable.  The delay time doesnt have to be extremely long either,
just enough to get some short ideas going.
