I'd love to see some pictures of that one... just for inspiration.

None of the comments on there are mine and the original bid raiser was apparently a putz that welched out when it came time to actually buy. The truck was listed again shortly after and I bought it at his BIN level although I don't recall exactly what that was off the top of my head.
Even as a time capsule though it still needed new suspension and that led to some other stuff and I tossed a set of 33's that I had laying around the garage on just to fill the wheel wells as the OME springs give a couple extra inches of height. Diff's will be swapped within a month or so. Beautiful little strippy and I don't care about fancy stereos or electric windows, etc. so it's just right for me. Less stuff to go wrong.
I'm inclined to wait and watch quite a bit though as impatience can cost thousands upon thousands more than I expect when I eventually pull the trigger.
Good luck.
