Gimbals are great!
I really like my Manfrotto 393 Gimbal.

When I purchased mine, many years ago, the price was about 60% of what is being charged now. It was a fantastic value at the time and isn't so bad right now!
Unfortunately, IMO, Manfrotto has the poorest marketing of any company I know of... They have changed the numerical designator of this mount several times and have also changed what the mount is called at least twice. They now call it a Heavy Telephoto Lens Support...
They also persist in illustrating the head with the camera attached in this manner.

I and anyone I know that has used this head always mounts the camera in this configuration.

See the two images with the camera mounted "over" not "under" the swinging U-shaped support.
I can adjust my Manfrotto Gimbal so that only a finger pressure is needed to move the camera lens. And, as far as weight capacity: just take a look at this image from Romy Ocon, the great Philippines Bird Photographer. Now that's a load to support

Here are shots with a Canon 30D camera wearing a 400mm f/5.6L lens and using the Manfrotto Gimbal...

As far as pretty poor marketing goes, early in my career with the Manfrotto Gimbal, I contacted Manfrotto asking how I could use this unit with a flash. The Manfrotto Gurus, in their ultimate ignorance, assured me that use of a flash with their gimbal was not possible because you cannot switch the camera to the portrait configuration with a flash attached. This image proves that the Manfrotto "experts" are certainly not "expert" and are certainly not cognizant of the capabilities of their unit...
That flash bar was fabricated from a piece of aluminum stock. If I were doing Manfrotto's marketing, I would have a flash bar available as an accessory, rather than telling customers that the unit could not be used with a flash.
