Sportsmansguide currently has new British military surplus desert camo gore-tex jackets and pants advertised. I bought a couple pairs of the pants for $25 each and a back ordered jacket for $60. I don't have them yet, but thought that I would pass on the information to anyone who might be interested.
Jackets = WX2-236237 (M, L, XL)
Pants = WX2-236240 (M, L, XL, 2XL)
They are also selling "windproof" desert camo for similar prices, but it isn't gore-tex.
