I read from one of the posts here that Russo Power Equipment in Chicago is a good online dealer. Their internet sales site appears to be down so I called them and was pleasantly surprised how comptetitive their pricing is. For example, their TBC-2501 is going for $229, while their TBC-230 is selling at $189. I originally just wanted a homeowner model but with these fantastically low prices, I guess I'll go for the commercial unit. I have to trim a steep hill with tall grass and some tree-like saplings with 1/8" to 1/4" diameter trunks. I am in VA and shipping was quoted at $15-$20. Not bad at all. So my questions are: (1) My budget being not-to-exceed $300, which model should I go for? (2) Are these brand-new units and not refurbished, and how can they sell them for so low? Thanks for any help.
