Lowa builds a great boot GTX Hunters are awesome, also look up Scarpa their Liskaams are pretty nice as well and a few bucks cheaper than the Lowa's.
I just bought a pair of the Meindl Perfekts from cabela's, just breaking them in they are very comfy. The sole is a bit stiff, but being a bigger guy (6'2"-280lbs) I break down boots pretty quick. Have had good luck with Danner Frontiers as well, but they recently changed the style of them and they now don't fit as well.
Lowa Hunter GTX's so I may have to go with the Pronghorns.
I would stick with the boots made in Europe:1. Kenetrek2. Lowa3. MiendlCoon
