I bought a 32pw6006 2 months back, and i think for the price (about £570 delivered from unbeatable.co.uk) that its a good set. The picture is pretty decent but sound is so-so.
Not seen any of the 4:3 problems mentioned in first post, however i do get dark rgb ...
The only niggling thing about the set is the scart socket i use to connect sky to the TV - it seems to give a very red, dark picture that I cant seem to normalise via the brightness etc controls from the TV menu. The only way I get round this is to pull the scart slightly out from the socket until im happy with the colour ranges in the picture - not a great technical solution, but it works (until the wife moves the tv, where the process has to be redone).
Im using a semi-decent scart lead, although not a good one from Ixos or simlar company, it is still better than the rubbish one supplied with the TV.
Otherwise, for £570 for a 32" Widescreen, i cannot complain...
(well apart from only having 2 scart sockets )
[While I remember, I saw the 28pw6006 in tesco for £399 the other week, which i think is a bargain.]
