I've narrowed my choices to either the Samsung DLP HLN507W w/ 1 year warranty for $3,849.00 or the LCOS RCA L50000 w/stand and 2 year warranty on the light engine for $3,599.00 Does anybody have any one of these RPTVs??? I like the RCA LCOS cause it's got built in HDTV and DirectTV/HD decoders (not to mention about $400 less) I saw the Samsung DLP at my local Circuit City and it totally blew away the plasmas that were next to it. The problem is I don't see the RCA LCOS on the Scenium website. Is the L50000 being discontinued??? BTW they are both 50 inch sets PLEASE HELP!!!
