I am looking to buy an OTA HDTV Tuner for my TV and was wondering if anyone had any direct knowledge on the LG tuners? I've looked around the web for information on the LST-3510A and LST-4200A. I've read alot of nice things on the 3510 but can't find much on the 4200. I don't really need the DVD player but the 1080i output would be nice! I've also looked at the Samsung SIR-T451 but alot of people complain about the picture distortion when zooming the 4:3 to 16:9 and vice versa. The grey panels seem to annoy people too. Any insight or help would be appreciated. Thanks!
