I'd have to echo Pikey's words of warning about Berghaus - almost certainly Asian imports. That said, Scarpa are manufacturing in Asia too. I bought a "cheap" pair of Scarpas recently for walking in tough but DRY terrain and they were very impressive - walking comfortably out of the box. I'm told that the field guides in the British Antarctic Survey are keen on Scarpa kit.
Gurnard - my other boot is a pair of old Meindl Burmas - they have done sterling work in the wet over many seasons and are going strong. For Scotland (and Ireland) I'd probably recommend the Meindl Butans for the extra bit of collar, but my Burmas have kept me dry. Made in Germany.
Hanwag are another German boot outfit that look to be excellent, if pricey. donegaldan wears them continuously* and seems to squeeze a few years out of a pair - and he's VERY sore on equipment!
