having only 20-30 SACDs, when my xa 777es needed a new laser/drive sled, I just had it fixed for about what you're looking at. it had twin lasers and both with a motor came in one unit. Once done, it was vastly improved.
however, I went another direction as my SACD supply was limited, and now do pc + HDD based music with no regrets. Albeit, I use an outboard DAC and don't have to rely upon my processor.
In your case, I'd do as suggested above, repair your's, try some other (s), or buy a Sony 777 or xa 777, or even a Marantz 8000 series, or if no Blue ray is in house, that Oppo BD 83 sure looks inviting. With the 1.3 HDMI you'll be able to use the processor that way or if no HDMI via the analog out of the players. I'd think too, the sonics will be vastly improved upon over the Parasound CDP.
In fact I plan on getting an Oppo blue ray later this year.
