I got mine for $150 from a fellow AS member... (you know who you are!)
Nice saw! (I wouldn't pay over $225 for one, but that's just me)
Before I bought it, I went to an auction last summer. It was a rental place going out of business. I went early to check out the saws, they had 2 ms260 pros. One was pretty rough, the other looked good. I took it outside and started it, It ran decent, idle was way high and chain was loose, but I thought for the right price I'd pick it up.
I bid up to $200 on it (it was a "choice" auction, I hate those), the damn things went for $365. They were RENTALS! People get crazy at auctions.
