Motorola Milestone :: Best Case For Phone That Won't Cause Issues?

Well I picked up a cheapy leather pouch style case for my Milestone on ebay, unfortunately its one of those ones with the magnetic flap which seems to be sensitive enough to trigger the magnets used for detecting if the phone is in a multimedia station or a car dock. If I put the phone into the case top first, it shows 'connecting to multimedia station' in the notifications panel, if I put it in the other way it launches the 'moto car home' app (even if the phone is locked and screen off, it launches, turns on the screen and unlocks it).

So the question is, whats the best case that works and won't cause issues? Telus so far doesn't have any actually stocked that I've found, and the one they list on the site looks suspiciously like the one I got. I'd prefer one with a belt clip but its not essential.
