Hey guys, yeah- been awhile since been on here; been thru another craftsman but now am the proud poppa of a Stihl 251. I can only ask myself why I waited until now after having been thru the low pro semi- chisel chain, the Oregon bar and diamond chain. This thing chews and chews, what I'm thinking in the back of my mind now is about sharpening; am I better off taking in to the dealer(not really a fan of machine sharpening) or investing in/ reusing my bastard file setup that I used on the craftsman. Anyone else have an MS 250/ 251?
