Hi bfast,
No personnel experience on this topic, however, I noticed the warranty issue in a prior thread. I couldn't find it for you, but maybe some one else can help. If you are going to buy on ebay, you should ask the seller, before you bid, if he has a HT setup where he could test the projector for dead pixels, or other problems. Chances are if they bought during the Dell sale, they are an HT enthusiast. If there are problems then they could settle with NEC. I would bet some have tested them already. I would also make sure you get the receipt with the purchase and pay the extra couple of bucks for shipping insurance just in case it is damaged during shipping.
From what I read here there seems to be no problems with NEC customer service, however, I haven't read of anyone buying second hand and having warranty work done.
Best of Luck
Todd
Does anyone have experience on this issue?
