I'm in the market to purchuse an small to mid size machine. I seen a General Wire Mini rotor XP Model # PX-P is this a good one to start out with?? Most of the call I been gettting is clogged tub drain or floor drain in a basement?? I just got to thinking of all the money I'm turing away! The line sizes I'm tring to stay in is 1 1/2 - 3" is there 1 machine that can do that range of pipes ??
