I’ll second the recommendation to wait (if you have patience for your DTS issue). I would have done so till late fall, but got in a hurry due to another purchase.
I had picked up a Sony DVP-NS715P for under 200, (impulse moment), which was extremely capable on the video side. (12 bit / 108MHz). The pic was excellent, and I would have kept it for that alone, - unfortunately my unit proved a buggy lemon, so it went back. I followed reviews a short while when I returned it, and although the postings were few, (it was just released to market), my experience did appear to be an anomaly. I’d recommend it (after careful checking on current reviews) for the video alone if your not trying to add SACD or DVD/A. But as Sanjay pointed out the price is dropping on units with one or both extended audio formats and there are a lot of goodies out there. However, I found they still don’t make one with the DAC’s I want with the other features I would like in any all-exclusive unit at any price, a few months ago while searching.
Once I had viewed the difference Prog. makes on a 60” (faults in your source are glaring at that size) I went ahead with a buy. I kept a Panasonic RP-91, as it addressed some concerns about aspect ratios for me, was satisfactory on video, and included DVD-A. I am very content with the 91 (Killer fast forward (who cares) but hilarious to watch, being so seamless as to appear filmed at that speed). Since its technology is aging (Genesis chip), and the price has dropped, it appears a good deal relationed to its original price for a well regarded, battle tested unit. I was trying to take a closer look at the RP-82, it was still unavailable at the time, I can’t remember if it supports MP3, I would assume it would?
That said, although I do recomend the 91, if I had already owned a Progressive player, I would have passed, (letting the price drop more, if I had decided for it) until I at least saw what the fall had to offer.
