Watch long enough and you'll find one for a decent price. I almost didn't buy mine because there was so little there, but when I stopped and thought about it, I realized that even if it had been functional, I'd have probably replaced all the pieces that I had to buy anyway.
I wouldn't be too jealous of your friend. I'm pretty sure that either of my sons (12 and 15) could easily rebuild an 8274. There's just not much to it. Going through a planetary is something else entirely.
Take a lot of pictures when you go to Choccolocco Mountain. Some of us need all the inspiration we can get. I've been doing some shakedown runs in mine and getting some bugs worked out, but real wheeling is still on hold until a few more things are buttoned up. What's killing me is how many really great wheeling areas are so near. Living on the edge of the Ozarks has it's advantages. Trails, Rocks, Water Crossings, Mud, and even sand dunes if I'm willing to drive the 300 miles to Little Sahara to get sand packed into every open area and bearing in my Jeep.
