OK, here we go. I'll start at the top. AFTER MODS, the MS201T is the top dog. That includes build quality, power, throttle response, handling, etc. You pay for it too, as you already know. Unfortunately, out of the box, it's a complete dog. That easily rectified by sending to me for $50 + shipping, or by following the instructions I've posted on exactly what I do to them. I have customers that would not go back to a 200T. They really come around that much.
