I'm looking for a reverb unit for under $300. It can be either a rack mount or a pedal, but has to have a wide variety of reverb. It can also have other effects as well, but I'm mainly just looking for reverb that can be bypassed with a footswitch. Anybody have any ideas?

Here's a list of some that I've found that are under $300:
Lexicon MPX-110
Alesis Midiverb
Digitech S100
Boss RV-5
Behringer V-Verb
Alto Alphaverb
Peavey Deltaflex
