IMHO, Oppos were overpriced last year when I bought my Tosh HD-A20 last June. They are still overpriced now. You can get Anchor Bay scaling (not de-interlacing) in a Tosh HD-A20,30,35 for under $200. You can get Reon scaling in a Tosh HD-XA2 (most say it's better than the Oppo 980) for under $300 on Ebay. I can get an Onkyo universal player (DVD, SACD, DVD-A) from Fry's for less than $200 (unless I read the price wrong).
Now, I have to call BS on you dissing the HD-A2. I have an A2 in my bedroom connected to a 768p LCD via HDMI. It plays 4:3 material just fine. I mean scratched, rented SD DVD's. It feeds Dolby Digital/DTS via Toslink to my POS Sony receiver without any problems.
I just did a quick search on eBay of completed listings for the Toshiba HD-XA2. Although it is true that a few of them have sold for less than $300 (not including shipping and handling fees, which put most of them over $300 that one must pay), most have sold for more. And these are USED units. Brand new, from Amazon, one can get an Oppo DV-981HD for $229.99 with free delivery. The Toshiba scores slightly lower on the Secrets of Home Theater and High Fidelity DVD Benchmark test—see:

For DVD playback, the Oppo has some advantages (faster to load up, does not pause for layer changes on DVDs unlike the Toshiba which pauses for 1.75 seconds [see above link]). The Oppo also plays SACDs and DVD-Audio discs, does a good job of converting between PAL and NTSC, and is easy to make region free.
The only advantage of the Toshiba is its ability to play HD-DVDs, which is a dead format. If one has HD-DVDs, then it might be something to buy. If one does not need or desire HD-DVD playback, it is crazy to spend more for a used player that does a worse job with DVDs.
By the way, the Oppo DV-980H that you mention is only $169.99, new and delivered, from Amazon. How is buying an Onkyo universal player "for less than $200" such a bargain, and buying that Oppo universal player for less than $200 overpriced?
