A bit of " Insider Info".. Almost ANY Blu-Ray player up-converts DVDs' to 1080p. If you have a PS3, you already have a Blue-Ray player that up-converts DVDs' already, just drop the $20.00 for the hand held BlueTooth remote so you don't have to use the gaming controller.
If you're gonna drop the better part of $100.00 on an up-converting DVD player, just go to the cheapest BluRay player ( $160.00 is now entry level ). Personally, I've only had a bad experience with the player trying to upconvert screener burns, on rentals, it's as good as it gets..
Actually, come to think of it, since I found out that my PS3 upconverts DVDs', I haven't used my upconverting DVD player.. I'd let it go real cheap, but realistically, it's worthless. It was just a stop gap platform that stopped making sense once the price of a BluRay player dropped under $200.00
