As Andy has said, please ensure if you get a Plasma it has all the correct connections on it.
Mine has 2 scarts (one RGB), 2 sets of component inputs (one for HiDef progressive scan), 2 sets of AV, PC RGB input, S-Video and it has a built in tuner (which is pretty useless as I have SKY+).
You have to ensure also that it has a high contrast and brightness ratio's for truer picture definition.
Connect one of these beutys up to either a progressive scan DVD player or Hi-Def on a XBOX and prepare to have your socks blown off!
