I have a PMX and was in the early first group of owners.
Yes, I would do it again, even though for me the learning curve is steep, and at times is still steep, even after a year. But then I came to the mount without prior experience of any kind in terms of high end mounts, computer control, etc.
My worm has been perfect out of the box, and I've suffered zero slippage even with my 12" CAT mounted. Uncorrected PE is under 2 arc sec!
I don't know enough about AP mounts but I don't think they have absolute encoders. I love the fact that I can begin using my MX literally in a few minutes of starting up. Once the mount moves from parked to home position no further adjustment is necessary to begin using a previously stored pointing model...in other words no synch is required at all. I have used the same model for months. And these super models give fantastic polar alignment information and terrific pointing, and data collection for T-Point is fully automated. You can decide to run a 400 point all sky model, start it and walk away until it is done. Amazing! The new upgraded camera plugin is really becoming sophisticated. The guiding screen is excellent and dithering is promised shortly. Bottom line is I can't imagine you wouldn't be thrilled with this mount, and from my experience on the SB forum, if you have an equipment problem, you will get help and the Bisque brothers will do right by you.
