effects racks?

["Tony Hughes" <hughes.tony@gmail.com>]

I've been looking into rack based effects processors to use while looping.  Wondering what people use to create ambient/interesting effects.  I will mainly be running a keyboard through the fx insert loop on my repeater, but will also be using my harmonica/vocals and anything else I can think of to make sounds.  Delay/Reverb etc...are all great, but I'm also looking for interesting special effects sounds (the crazier the better)...Would have to be stereo based and hopefully include a 24bit processor, but not break the bank.  Thought I might ask the list.
