I wonder if it is a scam ad? It looks about identical to the one I saw listed conditionwise.
Yes, grab it if it runs right. The older 85's seem to be better machines than the newer 86's with their epa crap. Mine is 11 years old and still going strong, and I've uesed the snot outta mine. Only thing I've changed on it is the feul filter, and that was just this year.
