I didn't find a forum for hardware review type stuff.
I just finished setting up a "sabrent usb 2.0 sharing switch-Model USB-SW20" to share my keyboard and mouse between 2 computers.
The thing isn't that is worked (it does) but it is CHEAP. $9 with free deliver from NewEgg. It came with 2 pretty high quality feeling USB cables, which would have been more than $9 at Wally World by themselves.
Just google "USB-SW20".
There is a similarly priced USB 3 one too.
