I have been using an Etha since before Christmas last year. I love the thing! I have owned both a Proto Rail and an ETEK. You can not go wrong with either one of them. I still have an ETEK but, use the Etha instead. Personal preference from experience, I would stay away from the Dangerous Power stuff. I had two and both had solenoid problems. The good news is they were cheap to replace (under $40 each).
