Too much money to take a risk with....and the price is just too inflated. I am pretty sure that I heard that you are not covered if you buy outside of ebay (but maybe that was if you didn't use paypal as well???).
The seller is trustworthy BUT, that is way too much for that bag, it retailed for $400! There WILL be another one, just wait it out, you WILL find another one at a much more reasonable price.
