WOAH!
Andy, Andy, Andy - what a great find, and a dream machine to boot! The MAH3000 in my basement is very jealous right now ;-)
I've always wanted to try out the Tony Tool, but could never stomach the cost since I can't imagine doing a bearing job more than once or twice on these. Since the factory bearings are still good (crossing fingers) on the 3000, I hope to not need to change them out anytime soon.
I keep waiting to find a 7500 locally for next to nothing, but the ones I run across still seem to be in good enough of shape to warrant a decent asking price. The 1000 RPM spin is to die for, plus touch controls, easy diagnostics, a heater... (I'm pretty sure the 3000 is going to kill me now)!
