I like cool ,,,, but when ever I do cool my other hobbies suffer , my machine gets moved around constantly from one part of the garage to another . one reason I bought it was the convenience over a stand alone . one of these days we plan to replace the old wheels with the larger nylon style so weight wouldn't be a issue .

Having had my Powerpro for over four years now, in daily use, I've had no problems at all. But you should keep in mind the following:
A) 10,000 rpm is a high upper speed and run for more than a few (10 or 15) minutes, it will get warm in there. There are no good reasons for operating the Powerpro at max speed - even at 10k the SS is a poor router, so you are better off using a router plus table for routing work. If you run at normal operating speeds (250-5000) you will not encounter heat problems. I never have.
B) It is 10 pounds heavier, the lift assist is very helpful.
C) The most common killer of Shopsmiths is sawdust in the headstock and the Powerpro is as susceptible, if not more so, than the conventional headstock. I built and installed a HEPA filter system with powered fan which keeps all dust out of the headstock, permanently - it maintains a positive overpressure, so air blows OUT any cracks and joints, so dust cannot get in. Since doing so I have never had any issues with sawdust.

The Powerpro is a considerable improvement to the Shopsmith, not merely an expensive substitute for a speed reducer. It will run in reverse (handy in drilling, sanding and for use with many SPTs); it maintains torque through continuous computer controlled adjustment, meaning it cuts and drills much better than the conventional SS. It has a wider range of speed (250 on the low end, very handy for lathe work and other stuff. As I said earlier I don't use the higher range; SS should really have given it a 50-5000 range not 250-100000)
It's also lower maintenance.
