I haven't used a Cambo for a few years, that was a UST with geared arm. Nothing wrong with it at all. But I now use Foba and love it. Silky smooth operation and for stuff like fashion, you can balance it so it floats and with the long arm you can pull back, rotate, move in, raise and lower without having to move the base and column (just watch out for clients with the other end of the arm!). One difference is that the Cambo's arm rotates around the column. The Foba's column rotates at the base (depending on models etc.).
The best thing would be to try them out and see which suits your needs and budget. Cambo is great value and Foba costs more. You get what you pay for, apparently, all thing being equal.
Whichever you get, I'd option for a tray and low angle bracket.
