thor,
on the msp craigslist there is a 066 in Hastings for $450,
I sold the fella the saw, it's a pretty decent old 066 flat top, nice case, tank etc. It's got a new aftermarket P&C from Baileys (on when I got it, not running). I pulled a few things apart on it and gave it a clean bill of health The fella bought the 36" bar from me and all the spare parts with it, not long agoe (January 2010). With the wrap handle, original handle, 36" bar, new chain and a pretty decent used chain, it's a pretty decent deal for $450, even if it has the aftermarket P&C. He must have painted the case and recoil and diddled with it a bit.
I bought the saw from someone who had just put the new piston and cylinder on it, and had problems getting it running, it wouldn't rev up. Choke was stuck and the fella had no clue. It was a 1 minute fix and a little clean up. I pulled the muffler off just to check things out and it was just perfect. I'm not the biggest fan of the aftermarket P&C but it's not that tough to round up a nice OEM one.
