I got a 42" 60Hz model off Amazon not quite a year ago. The picture is actually quite nice on it. Motion blur is an issue, but I'm also used to gaming computer monitors (currently on 2D lightboost VG249WQE). Either way, it was a really good deal for the price! It didn't have many features, but I wasn't really looking for features. The build quality is surprisingly nice, and the TV (not screen) looks good.
I've heard that TCL often uses Samsung panels in their TVs. Not sure how accurate that is or which TVs it would apply to if so.
