I am on the verge of buying my very first plasma TV and am drawn towards the Panasonic Viera TH42PE30. I have a few questions that I would really appreciate some input on : - Is this model High Definition (and therefore future proof to a degree)? - I notice some ads have a B suffix. Does this denote extra features? - Is it easy to self-install (for a novice) and connect to my Sony Home Cinema Kit with sub-woofer etc currently connected to a Hitachi Widescreen along with VCR and DVD player? - Is the extra warranty cover advisable (I know this is where the high profit comes in for the retailer)? - is this considered a good buy viz-a-viz similarly priced alternatives? Many thanks in anticipation. I have found this forum really educational with some great pointers so far on what to avoid etc.
