The 8500 is an easy to use, very practical tool. If you had never used one, you could pick it up, and use it immediately with great results.
The Microvibe is the best all round piece of equipment I have ever used, but I find the controls are not intuitive (to me anyway) and if you are not using it continuously, you have to learn it all over again.
I have used the VXP, but I have to tell you that I had a serious problems using the solutions it proposed and the outcome it generated. In fairness, I suppose that I have experienced some problems with every system that I have used if it is followed blindly, without a little bit of operator intelligence.
Sometimes track and balance adjustments don't all move in straight line mathemetical functions, and there is no replacement for a little bit of human brain power, intuition, and suck and see!
