I have been using a generic USB 2.0 hub (as the Pi 3 only supports USB 2.0) - £3.40.
It has been working well for peripheral support (EQMOD mount and usb focuser). Haven't tried it with the camera. Powered it from the 12-5VDC step down converter that is powering the Pi.
Note: After confirming it worked OK and mounting it next to the Pi, I attacked it with a soldering iron to remove the very bright blue LEDs.
