$500-$1000 to spend on a used CD player

I was thinking of upgrading to a blu-ray player for my HT system. I was seriously considering the Oppo 83. I was however thinking of buying a used CD player for my two channel system. I would gladly buy an Oppo if I could find one used, but I doubt that would happen. I am looking more for suggestions for a good used CD player.

Regarding the Oppo BDP-83SE. Is it really that good of a CD player? I am always under the opinion that a CD player should play CD's well. I guess I am suspicious of the sound quality due to the fact that it is also a DVD player and a BluRay player. Also without being able to listen to the Oppo I would be nervous about purchasing it new sight unseen. Is the sabre DAC on the Oppo worth the extra $400.00 over the BDP-83 for $500? I could buy a pretty good DAC for the extra $400. I thought if I bought a used player off of Audiogon sight unseen and I decided that I didn't like it I could sell it for close to what I payed for it due to the fact that I bought it used.

I'm not necessarily concerned about resale. I just don't want to buy something I haven't heard and then be stuck with it.
