I got pretty much all of my airsoft gear from either ASGI and Evike.com. However, most of my gear and equipment came from a variety of sources including my uniforms mixed between both my Cadet issue and BDU.com, and my boots from a number of sources, including
Vermont Army/Navy, and
www.militaryboots.com with a few personal purchase items coming from a local surplus store across from the Texas A&M campus in College Station (primarily Sarge's).
My LBE and personal equipment come from a variety of sources including eBay (nearly all my ALICE stuff),
Tactical Advantage, Vermont Army/Navy,
Spec Ops Brand (love their MOLLE/ALICE compatible gear and packs),
US Cav Supply,
Ranger Joe's,
California Army/Navy (and their eBay store),
Alleghenny Wholesale (and their eBay store), and
The Supply Captain with nearly everything being either US surplus or new Berry Compliant equipment. I don't use everything I buy from these retailers for airsoft, and use a great deal of it for field and camping equipment related to my geology work since I find a lot of military stuff now is cheaper and at times even more durable, rugged, and packs tighter than commercial stuff, a huge plus with me beyond simple familiarity.
