You might also look for a different used player. There are universal DVD-A/SACD players from Denon, Yamaha, and OPPO as well as ones from Pioneer. I've used several of the OPPO DVD-A/SACD players, and you may be able to find a used 981HD or 980H for under $150. The 970HD would also do what you want, although it may cost more - it's the only one of those players that can be made to scale DVD output via component video, so there's always been a bit more demand for it on the used market. THe 983H would also work, but they still sell for their original $399 list price (or sometimes higher) on the used market.

If you did get the OPPO player that's due to be announced this week (and I'm guessing that $300 is a reasonable price point to expect), it would also give you Blu-ray.
