Can anyone give me good reasons to pay 14K for the Marantz VP12S4 as apposed to 10K for the Sony VPL VW100. The Marantz is 720P and the Sopny 1080P. The Marantz has gotten rave reviews, but I'm trying to figure out why the price difference. If you had the money, which would you buy? Any explanations would be great.
