250 Stihl does not impress me much, better saws out there for the money. I think I would end up giving the Echo a try.

I've got both, and I am with Mike... the 250 doesn't impress me much. My CS-520 absolutely rips with a 5 minute muffler mod and re-adjusting the carb.
My vote is definitely the Echo.
