Should be great, especially at the price you can score a 51". I got the 65F59 and it's excellent. The colors vibrant and have a great pop effect and the image is very 3d-ish on upscaled dvd. I think you'd be more than happy picking the 51F59.
2 guys I work with got the 51, and the boss got the 65. They all love their new set. I helped one of the guys set his up, calibrated it with Avia for him. This was his first move into the HD world.. he is hooked, along with his family. He purchased in May, since then, he has purchased a new receiver, new dvd player, new speakers... tell me he's not loving it. That set is easy to tweak also.
