I’d rather get automotive advice from votblindub than get anything tv related from you 
do NOT judge DLPs by what you see in the showroom. They mess with those tvs horribly. Either feeding them subpar signals, messing with their settings, and/or usually putting them in the furthest corners of the showroom. Every single salesmen will be happy to point out all the disadvantges of a DLP and point you to an LCD/Plasma instead (they get more commission). A properly setup DLP will be just as good as any LCD/Plasma.
