Meade ETX was one of the worst for this. Not sure how good they are now.

I owned an ETX 90 long time ago for while, sounded like a coffee grinder.
New redesigned version is out, not sure how good is it?
Newer ones the OTA removable!

Technically, so are the old ones, but it's difficult. They do have tripod mounts to act as spotters.

It looks like that middle gear may be too loose on the fixed shaft and is wobbling. You could try removing the gear and putting a thin layer of heavy grease on the shaft before reinstalling the gear.

All three gears could stand a thin layer of grease on the teeth to cut down on friction wear.
