Let the buyer beware...there will always be a variation on all . We have actually done part of installations with customer purchased components...no problem...we do not warranty their purchase, and will let them know time/labor costs will be incured for their purchases if failure or improper operation (or none at all)arises. Our plasma purchases are delivered by our distributer and turned on at site to verify operation (sometimes we use this service-depends on 'busyness' of our trucks )...On line savings on fragile components like plasmas are subject to the buyers perspective...thats all...no bashing
