This is a great set. Vizio's bread and butter for many years. LG S-IPS 42" panel (excellent off axis color fidelity), wide viewing angles combined with rock solid MediaTek video processing. 120HZ is a nice extra on this set to deal with varying source cadence/deinterlacing/judder playback issues.
All brands have horror stories.
Vizio warranty service has been as good as any, better than many. They are headquartered in the US.
