Sony S5100 has a cracking picture, and seems snappy enough. or at least it is on my dad's home system. Be aware that a lot of these budget machines (S5100 included) only have a digital o/p, not analogue, if that's an issue to you.

Panasonic, Pioneer, and definitely Oppo are also great if budget allows. Personally I'm not a huge Samsung fan, having had a couple of machines in the past which weren't great.
