Tripod Dolly

While we have a decent [gimbal](https://github.com/dwyl/video/issues/50) which is useful for moving shots, we don't own a [slider](https://github.com/dwyl/video/issues/47) or tripod [dolly](https://github.com/dwyl/video/issues/58) for 100% smooth shots.
Last week when I was filming the "Making of" for the Attic Stairs https://github.com/dwyl/home/issues/136, I felt that I could _definitely_ have used a dolly for smooth movement shots. And in a "classroom" or "meetup" situation where we want to move a camera without shaking, a dolly is the professional way of doing it.

A few months ago I looked into Dollys, but the "good" ones are _expensive_
and the "cheap" ones don't look particularly heavy duty.
The Amazon's Choice for "folding tripod dolly" is the "Andoer Kingjoy VX-600 Pro":

Even though the reviews are _good_ it's still "consumer" grade, not really "professional".
Having said that, if the Manfrotto (below) is unavailable, I will order the Andoer and test it. 💭

Google translate: Basically new.

I sent the seller a message on OLX asking if he still _has_ the Dolly.

For reference, this Dolly costs $399 +shipping in USA:

Review the related gimbal, slider, and dolly issues (#50, #47, and #58), plus the filming context in home#136. Compare the linked Manfrotto and Andoer options and confirm availability; the work is complete when a suitable dolly is selected, acquired, and tested for smooth camera movement.
