I just bought a 250C-BE recently and love it, except that I am not overly found of the chain tensioner as Stihlhead eluded to. It gets all gunked up with stuff and takes extra time to clean up, but it does work. What I really love most about it is the "Easy Start" feature and primer bulb that also comes on the C-BE model. I'm not getting any younger, and have a very bad left wrist, and can forsee a time down the road where that easy start will make a big difference. Either way, can't go wrong with a 250 for $299, or the C-BE for $50 more.
