I have two different Danners, a pair of the Mtn Light II and a pair of the Romeo Work Boots (which are no longer in production). The Mtn Lights are MUSA and the Romeos were made in China. Both are top quality and I'd recommend the brand with no reservations.
If you're interested in the Jack II, you may also want to consider the Rancourt Byron - I have a pair of those and they're great for everyday city use. (and made in Maine)
