After reading this Forum and doing some research, just bought the Echo PB770T. What a machine!!! Went together easy, started right up. I have 2.5 acres with ponderosa pine and needles everywhere. This thing makes quick work of a project I have dreaded for 4 years. It moves the needles effortlessly, no more raking...yahoo! The only thing that would work better is probably a Cyclone Rake, but couldn't do that this year.
