Can anyone comment on Skywatcher AZ4 or GSO ATZ mounts?

Looking for not-too-expensive altazimuth mount for a 150mm Skywatcher Mak.

One of these two mounts may be the way to go. Anyone had any relevant experience? Help please.

I've got the Bintel version and I am extremely happy with it, since it is a cinch to just pick it up with the telescope attached, and take it outside. However, my MAK is the lighter Skywatcher 5".

Sometimes, when I attach very heavy eyepieces to the telescope, the up knob doesn't work, which means I have to rebalance the OTA slightly.

Regards,
Renato

I have an AZ4 that I have used with the Skywatcher 150 Mak. It's about the limit for this mount in my opinion. The tube weight causes the friction to increase on the altitude bearing and it starts to get 'sticky' if you go any higher. Otherwise it works well.
