Anyone have any experience or thoughts on the Craftsman propane powered line trimmer from Sears. I'm in need of a new trimmer and prefer to stay away from mixing gas. Battery operated ones are ok but you can't put an edger on them. So this one would give me, hopefully, the best of both worlds. No gas mixing, enough power(?), better for the environment (less pollution) and versatile. But its new and I hate to buy in to a bad idea? Anyone with any thoughts or testimonials welcome. I went to the store to check it out and there were 3 in the return bin. I asked why and of course the store folks had no idea. I was really wondering why they were coming back. Perhaps it was the manual (professional style) string loading.
