This one easy. Ada duit LED, kurang duit LCD. Both works just fine. LED is a actually too bright for prolonged viewing. Nicer blacks...but you need to pay extra RM1K++ for equivalent size.

IMO, is good time to buy LCD now, coz it'll be phased out for LED....can get 40" for rock bottom 1.8k....i just bought a Sharp 40" LCD for RM 1.9k

Just to add to the above article:
The 100Hz thingy is worth the money when it works. Best i saw is Philips HD Natural motion, Sharp's new LED 100Hz and Sony's Motionflow. Those korean 100Hz not really can use....
