The LG one we have at work. brand new this month. 8 of. Nice piccy, not one dead pixel in sight (but it is early days yet).
Cant comment with a comparison to the rest though..I can't afford to buy all four, and then use the best. and the Boss just picked one TFT and bought 8 the same, rather than buying 8 different 17" ones.
LG stuff from my experiance is quite good though.
Have DVD/CD-RW (3/4 year old, still going fine).
A video. It is the longest lasting video i have ever bought for under £100. (the last one, not LG, lasted 375 days, ie 10 days longer than the warranty, never buy from that well known electronic maker again). The LG one, now over 2 year old.
