Friends of ours have a Salem; we have a Grey Wolf...
We prefer ours.
The lack of carpet in the Wolf makes keeping the floors clean a breeze; fit and finish is very close between them.
2 k, on a 20k purchase, really isn't a deal breaker one way or the other... All things being equal, pick the one you like; but based on our experience, the Wolf was a better choice for us.
