They are like 240.00 with a speedfeed
One of my buddied bought one and used it for a few weeks, concluded his Rotor fed just as well, and didnt have a problem loading paint into the hopper. He said when he used the speedfeed he would really have to shake the tube into the hopper to keep it from bunching up on the top of the spndle.
As far as a speed rate, it will keep up with anything you are shooting with it, there is a cool reball video of it on constant cycle with it feeding paint right back into itself.
Sometimes It's Good to be EVIL
