So I ordered an AZ4 instead. Construction seems really nice. I opted for the 1.75" tubular steel tripod instead of aluminum. The whole setup is quite solid with some good weight to it.
I've had limited use of it so far but it seems to be just what I was looking for. I wanted a tripod mount that would offer the same smoothness, stability, and simplicity as my Dobsonian mount. The AZ4 fits the bill. Like my Dob, it glides on teflon bearings so there is no sticky grease to contend with. Tension is controlled by a large knob on each axis. I keep the altitude tightened all the way and it works perfectly. Very easy to move but it stay right where I point it, even after switching to a heavier eyepiece. The pan handle can be fixed in two positions. I have mine in the lower position because it's easier to reach, but it this position the tripod legs get in the way a bit, so that's a small drawback.
Not much else to say right now. Once I try it with higher power I'll have a better idea of its stability. I'm really liking it so far, though.
