Well I did it. I got a logitech bluetooth MX 900. I ordered it from eCost.com and am extremely pleased with the process. They have a service called Borderfree, that calculates customs charges to ship products to Canada, so you don't get stuck with charges when the product gets to your door. Also their prices were so low, that even with shipping charges, conversion to Canadian dollars, and customs charges, the mouse was still cheaper than listed on the Logitech Canada website. The mouse is fantastic. While a little large, its very comfortable. I was able to map the buttons to whatever I want with GamePad Companion from VersionTracker. As for acceleration, I don't see anything wrong with it and don't understand the complaints of some people.
