First off, I have never heard the Prima, so I will not comment on its sound. Based on those who have, it seems to be pretty darned good though!
However, I do own the Opus 21, and I love it. My friend upon hearing mine, immediate went out and bought one, and he too loves it. He compared it to his Theta and quickly sold his Theta. He even bought a Esoteric DV-50 thnking it would beat the Opus, and sold the DV-50 after comparing it. (I will point out that both my friend and I are both primarily into analog, so we were both looking for a good redbook player that sounded close to the analog sound. We feel we found it in the Opus 21.)
So I highly recommend the Opus 21. If you can afford to buy it new from Resolution Audio, do so, I doubt you would regret it. (By the way, Jeff, the owner of R.A., is a great guy, and an asset to the audio community!)
However, if funds are low, then buy a used Opus 21, and if you like it keep it. (If not, sell it and be out almost nothing, since the used market is pretty hot for them.) There is one for sale right now on Audiogon for $2,500 including shipping, which is a pretty good price.
(By the way, the current price is $3,500 and the restocking fee is 5%, so that works out to $175, plus shipping, not the $150, you stated. It used to be $150 when the price was $3,000.)
Good Luck in your search!
