RPTV's can actually differ quite a bit, if you're willing to wait, Samsung's coming out with their HLP model's soon (thus the current HLN models will be cheaper, thus saving your dad money). DLP is an awesome technology. Many people over at AVSForum's have been quite happy with Sony's GWIII and the Samsung Series in any size. Mitsubishi is also getting a look too... It depends on how much HD content your dad wants to watch, as some TV's suck ass with SDTV and other's are OK at it, but maybe once he see's HDTV he'll be like "why was I ever watching this other garbage?"

yeah so it's more expensive... but they're damn good TV's, and with the Samsung's you can put them on a shelf of some kind, then put his DVD player and dishnet box under neath that, thus giving you more room :P
