I'd still prefer a Panasonic. But, it looks like you landed a good deal. Wait till the BD-35 either drops to $200, or even at the current price, or at current price with promotional BDs or the like. Use that as your primary player, and then use the Sammy as a backup BDP, primary DVD, and primary HD-DVD player.
Every once in a while I play with the idea of an HD-DVD player. If you ever wanna sell it, lemme know. I don't think I will... but... hmrz.
If you ever do get an HD-DVD to try out, check out The Thing if you can find it. Amazing transfer for its age and budget, and the Bluray version is not even close.
Oh yeah, you can enjoy the Bourne Trilogy.
The Pianist, and King Kong (Jan 20 is BD release).
Elizabeth, Apollo 13, Stardust, Casablanca, Feast, Dawn of the Dead (remake), Pitch Black might* be some not available on BD. These all have alright PQ, not reference, but enough improvement to be worthwhile.
