KVM switches are like the high-tech equivalent of a garden hose splitter; and I never thought I would have to put so much energy into finding one. The IOGear GCS632U I picked up at my local Best Buy lasted a whole three days before one of the USB adapters stopped working. Reviews on Amazon reveal that his is a somewhat common problem.
So, after some obsessive googling, coupled with intense scrutiny of just about every Amazon KVM switch review… I’ve gone out on a $50 limb with the tiny StarTech SV211KUSB Micro USB KVM Switch. And a week later I can still double Scroll Lock over to my Mac Mini. Whew!
Now if only I could get the Mac Mini to recognize my weird-ass wooden Japanese keyboard and let me double Scroll Lock back to Vista. Good thing the switch has a physical toggle.
