The best "lowest priced" new or used Digital Reverb in my opinion is the Roland SRV330, not the 3030. I had one for several years til recently. I sold it to get my new VS890 which has 24 bit processing. The SRV330 is AWESOME! Rivals Lexicon's PCM's.
The SRVs go roughly anywhere between 150-300.00 on ebay or HC classifieds. They don't make these anymore so snatch one up while you can. Good luck!
PS, what are everyones opinions on the 24 bit processors in the VS line of digital recorders? I just love the reverbs, but the digital delays are noisy and lack depth compared to my Chandler Stereo Echo Delay, which I just found out lately they don't make these anymore.
