I've used similar as far as the lift goes, but on a different base. The one I was using was a three wheeled self propelled type, primarily used for orchard pruning. It wasn't hard to operate, though I might suggest in your application setting it up and paying with it next to some trees for a bit to get a feel for the controls. If you go a little too far in one direction and brush a tree, no big deal. Brush a house with a metal bucket and now you get to paint/repair while you're up there.

I do agree about making sure the footing is solid and properly set up. The unit we used sat nicely on three points, but you could also drive it from the bucket, so repositioning was easy. Of course, you're not really supposed to go for long trips while up in the basket, and it was quite the ride, but I can see how having to come down and pick up the legs, drag the thing over a few feet, and set up again would get to be a drag.
