I just bought the Panasonic AE700 LCD projector and have a question about the lamp cost. The Panasonic web site lists the MSPR cost as $650 CDN, the local Panasonic dealer sells them for $600 CDN and I can get them off the web for $350 US. What is the cheapest price you have seen them for? Would anyone consider buying a new unopened one off Ebay? I just don't want to get ripped off buying a replacement lamp. Thanks.
