I came across a BME 50 real cheap which is a Kioritz/Echo SB1080.

I also walked into the farm store about 12 -13 yrs ago and there was a sign on a 22" Poulan 3450 60cc saw that said $75 as is. The thing was covered in oil but the chain was still factory sharp with no marks on the bar so I bought it. It has the good cylinder etc. But I still use it as a saw. There was nothing wrong with it that I ever saw.

I also have a couple latter 20" Homelite 45's from pawn shops - a red and black one and the last all red one. They are still saws also. Too good as a saw?

I have plenty of other gas engines.
