I've heard a lot of people are having to do some serious trimming to get the Atlasworkx DBM to function properly, which I'm not interested in.
My preference would be the Badger DBM, they have a military discount, and I really like that, plus they have great customer service.
In the end, $79 was hard to pass up for the PTG, and it's almost identical to the Badger, minus the small magazine guide that sticks down...similar to the Surgeon.
