Just wanted to chime in here regarding Ben's service: started the order process, got uneasy because it wasn't through one of the big-box sellers, and so put the brakes on as I did more checking on Ben and his reputation. Needless to say, it is sterling, both on here and on FM. Tons of reviews from 100% satisfied customers. I went ahead and purchased the item, and Ben went out of his way to make me happy. From then on, won't go through anyone else.
If Ben were a scammer, I don't think the admins on here would have allowed him to keep on posting.
In regards to sellers getting around Canon's price control: I may be wrong, but vendors have to list MAP, yet they don't necessarily have to honor it. Check out CPW and their Street Pricing via authorized sellers. Greentoe as well... there's ways around it.
All in all, it's good to have a VERY healthy dose of skepticism, no one can be faulted for that.
