Some room for improvement, but... - Cuddeback Cuddesafe Bear Safe for X2 Trail Camera

Not quite as heavy of steel as I would have hoped for, but definitely sufficient to discourage all but the most determined of thieves. It requires a little patience to get the camera out of the housing. Even just 1/4" of additional clearance to allow the camera to slide up would have been a big improvement. It goes in okay, but is a little tricky to remove. It's still the best option available given the fact that it's designed specifically for the camera.
