im pondering on getting one of the new dolmars. i was looking around at them a bit and i found the 7300 for 646.00 pluss tax and the 7900 for 721.00 pluss tax both with a 24 inch bar. my question is, is there alot of noticeable difference in running these two saws. i know the 7900 is a half horse or more powerfull then the 7300. is it worth the price difference? also has anyone run the 7300 against a 372xp and if so what was the outcome. The dolmars look and feel like a really nice saw . im seeing one in my future. just havent figured out yet which one its going to be. also would i be better off to just buy the power head and order my own bar and chain? or would the prices end up about the same anyways. . Thanks for any help on this one
