I'm thinking of buying a walk behind trimmer by Ariens. The reviews are good. I searched for Ariens dealers and it took me to Gravely dealers. Is the only difference, on this particular product, the brand name sticker? Also, the dealers in my state are one privately owned, successful full service hardware store and Home Depot (although it must be ordered online through Home Depot). I believe in supporting local dealers but wonder if the unit sold through Home Depot would be the same machine or a watered down version. Home D is actually more expensive. Also looked at a Husky model but it has a Briggs & Stratton engine. Ariens' is a Kohler engine. For some reason I think that would be better but I have nothing to base that opinion on other than the thought that cheaper stuff would use the Briggs & Stratton engine. One more thing--if the store has one now they have left from last year is that okay or should I get one from newer stock?
