Looking for compressor/effects rack mount unit suggestions

[nitrofix]

Hey Guys, Like the title says I'm looking for a single space rack mount compressor that has effects as well, octave, synth, ect..I don't like using pedals and since I already have a rack with 1 space available I want to go that route..Any suggestions would be great...Thanks again
