I'd agree with that. I bought this three years ago: https://www.amazon.com/gp/product/B0793TDNSX/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
It was $35 at the time, and by far the most useful feature it has is auto-leveling (by gimbal) in both the vertical and horizontal planes. This would have been all but impossible to mount without it: https://i.imgur.com/RfMqMPi.jpg
