I am pretty happy with this

For $44 I get 4 USB 3.0 and 3 USB 2.0 powered hubs with individual on off switches. I run a ($16) 4m USB 3.0 cable from it to the PC in my Astro-labs PCI express 2 port USB 3.0 add in cable ($59).
I have mains power going to a 6 port individually powered adapter that is velcro taped to the pier. So I run my imaging cameras power and USB connectors respectively from AC/DC adapters connected to the mains plugs and the USB to the powered hub. The HUb of course is powered by a 3amp mains converter also plugged into the mains switch on the pier. My OTAs focusers power and USB connections also go into the power supply and powered hub.
I haven't put the Guider (Meade DSI II Pro Mono) into the powered hub. This I could probably do without issue.
I also have a TempPerHum connected to the Hub.
The USB 3.0 ports are for if I ever want to run high speed video from the OTAs.
