Im set on getting a 37" after determining that my room is too small for the 42". Im set on the Panasonic PWD series, but from a few other threads it seems that the 37" does not live up to the PQ of its big brother (Which I demo'd and thought was gr8!). Has anyone seen them side-side or read any reviews? Is there any technical reason why the PQ would be worse on a small screen? (I would have thought better if anything). Do I really need to find a dealer to demo this unit as well? Really appreciate any views whatsover. Cheers, Nick.
