Been trying out my brand new Giro Ercole (bought from Teleskop Express).
It's finish is top class, and the mount is heavy enough to take my TSA120 and 120 Equinox with ease.
Altitude and azimuth motions are silky smooth. The resistance and lock setting knob are easy to grasp. Their effectiveness could do with being more gradual though, and total lock requires force with heavy scopes unless balance is perfect. Changing heavy eyepieces needs some deftness of hand to keep a scope from tilting off target.
Construction of the mount is very solid, the big knobs are plastic but everything else is metal and seems very robust.
Like Altair Sabre mounts, the Ercole is readily available, not the case for AYO II. I did not want a big Chinese mount as I already have a couple of Skytee 2s, which are outwardly rugged, but have minute grub screws, Quatermass grease and are fairly high maintenance to keep the mechanics working well, especially in winter.
The APM AZMaxload is next step up, but that's SW AZ EQ6 price class, and would also need a new tripod as well.
