Marmot, TNF, Mountain Hardware, HH, etc....all have high end mountaineering equipment. TNF usually has the most sales though, (and strangely enough the most knock-offs, outlets (genuine but no warranty)) so you can often get 350+ gore-tex parkas for about half. I was in that whole hiking/outdoors thing back in high school and bought enough gear to ascent Everest, but mainly stuck to summer hiking in my running shoes. I still have these funky synthetic shirts that stunk when you sweated in them...but it kept you warm even when wet.
