I currently have the ability to try out 2 different low end BR players, Samsung BDP-1600 and the LG 350c. The Samsung is the better of the 2. The LG (Running the latest firmware on it) appears to have some issues with loading some movie titles, the most recent one I watched on the LG was UP!, I had to turn the LG on and off a few times before it finally started reading the tracks right, it even had center channel dialogue coming out the Left surround speaker for awhile. We had chapter titles popping up on and off through out the movie. I played the movie on the Samsung and it had no problems at all. I am quite impressed with my $100 purchase of the Samsung.
I had the LG 350C for a couple of weeks as well. I found that it locked up a few times and ran pretty warm.
Recently I picked up a LG 360BD from Costco for $150 and it is miles ahead of the 350. It's actually the same as the LG 370C model...even has both the 360 and 370C model numbers on the manual...probably a special Costco version I guess. Regardless it plays just about any video format including DIVX, mkv, etc via disc and the front usb port and even has a youtube function that connects via wired internet. To update the firmware for this you just use the updates for the 370C. Very happy with this player for the money.
