Used Echo CS8000. Was a QV8000 which is basically the same. Only difference is that the QV has a manual oiler besides the auto oiler. Do not have a bar and chain for it or the felling spikes which are available thru Echo. A 27" bar would go great on this saw. Can be gotten from Echo or other bar and chain suppliers. Saw runs awesome. A new saw with same cc's will cost at least $1200. This one $375 or best offer.
