Hey guys, this is my first post here, but I've been reading for weeks now. I started a small service in North Dallas, and have purchased almost all of my equipment used. I'm currently using an Echo GT 200 trimmer, and I'm getting ready to buy something better. I bought the GT 200 used from a neighbor for $15, and it runs great, but I hate the curved shaft. The Shindaiwas with the C4 technology have really caught my eye. I know I can't go wrong with Stihl or Echo, but does anyone have experience with these Shindaiwas? My local retailer has the 2510 for $339 plus tax.
