Ive been looking for my first blu-ray player myself and was actually supposed to get it for Christmas but since I couldnt decide lol...
Anyways. I can give a little helpful info as ive done alot of reading.
LG370/390: If you want LG, youre gonna have to get the LG 390. The 370, which you can read on multiple sites, apparently has "lower video quality" and is also the older model with a few other issue. The LG390 is about $260 at BB right now, but it has like all the damn features youd want. I wouldnt consider the 370 personally.
Ive stayed away from samsung blu-ray players, partly because people seem to say they have some quality control issues. I am not sure how true this is but....
The panasonic bd60k/80k I keep coming back to. Its only $120 at Bestbuy right now. The only issues with it is, it doesnt steam netflix. Also lacks a bunch of other stuff of course but...its known for very good quality video and audio.
Playstation 3: I keep coming back to this and ive almost pulled the trigger on it but... PS3 obviously does everything and is a gaming system. It has a few negatives ive read. Supposedly the audio quality is not as high as other standalone players. I am not 100% sure if thats true but, ive read it on a few places. I guess PS3 has "not-so-great" dvd playback either, which is important for me .....
PS3 is also the most expensive option and you also need to buy a separate controller for $20, which makes it $320 before tax...
Pioneer bd320: Seems good. I had many people from this forum recommend that. Ive read that it has among the slowest load times though, which is unfortunate. Also, it does not stream netflix I do not believe.
Heres some sites ive been pulling some research from....
