I've been following the threads about these RTPVs and am getting quite interested in buying one. I would settle for the 42WH36P, as my sofa is about 8 ft. from the screen. I may end up buying this sight unseen from an internet source, as I haven't been able to find a single store in Berlin that carries any of these models. The German internet suppliers have a no-questions-asked return policy, where the buyer can cancel the purchase within 14 days and have the supplier pick up the merchandise at his (i.e. the supplier's) expense. Before I actually place my order, I was hoping to hear from people about the following: Has anyone out there had one of these beasts for at least six months or longer? Once you've got it set up properly (e.g. service level convergence), can you just sit back and enjoy it for years to come? Or do these RPTVs require regular realignment? Don't you void the warranty by opening up the set to do mechanical and electrical focus?
