At the funshow yesterday an older fellow with a small table had an all DPMS M4 preban, serial #1900s.  Asking $800, including an A2 stock, cheapo scope and mount.  Looked 90%, but had some stupid rubber buffer thingy installed that made it damned near impossible to take apart and caused the bolt to lock back on its own.  I had to slap the stock real hard to release it.  Besides that it looked nice, and what a price!  I offered my M444 FAL and all the cash I had ($85) as trade, but he would'nt do it.  Damn college sucks.  So poor...  Missed the deal of a lifetime I think.  

Wow that's gotta suck. Sorry to hear that.

I feel your pain!
