Recently, RyKie Images & Events became a Canadian (perhaps the only one in the country) reseller of easyCover products. I field tested a cover on my D90 Beast over the weekend at Spin Nightspot's St. Patrick's festivites.
The cover was great - seals nicely, feels comfortable, and adds more protection to the body. I was curious if it would interfere with regular shooting, and it passed the test. A few little areas could use a trim (around the shutter release and dials), but this is an easy fix.
I also purchased a cover for my D7000, and it fits like a glove. Only issue I have is that the bottom will need to be trimmed a little bit to accomodate the battery pack. Very easy fix, but if you have a similar grip, you'll likely need to cut off a bit of the excess with an exacto knife. Be careful - our fingers are our business!
easyCover also features lens bags and other goodies to protect your gear.
