Here is what I purchased this summer.

I think I got a good deal on it, but not amazing. Since then I have been keeping my eyes out for another one for a friend. I have seen the prices go mainly up since then, but not always. Sometimes junk goes more then good trucks do. My suggestion is be patient, and visit a few GL auctions that have them. From what I have seen military surplus does not just sit in a field for years, but it can become the local parts store. Oh they don't all have rust by the way even though it is common in the usual places under the door on the rocker panel, behind the rear wheel, on the inside floor right infront of the rear wheel wheel, etc.
There is a civi Chevy Blazer that is for sale up the road that the owner is asking $1400firm for. I believe that it is a good deal, and in good shape. I had considered buying it, but found my M1009 while deciding. It has about 180K on it. He has it out there since this summer when I was looking a Blazer even if I had to paint it camo. Anyways the body is good shape with only with a few small spots. The engine ran well, but the rear end did not sound to great. I might just not have been used to the noises of a blazer though. I think he replaced the engine recently, and had a GM replace the tranny at some point. It has a tow package, and was used mainly for towing a boat. If that interests you I have some pics of it I could send you.
