Bought from pricejapan.com based on price. I was a little careful and used buyer protection when I paid via paypal (an extra 20-30 dollars), but I haven't heard of anyone having a bad experience with them. Also, they seem to be fairly well respected in the high end a/v market, so they're not just zaurus people. They have forwarding service for the warranty (1 year), but I haven't had opportunity to try it yet.
Brett at conics.net has been known to be very helpful and reasonably priced, and dynamism offers full service (phone support, free repair shipping) at a premium (but I found they will negotiate a little).
If you have more questions just ask.
