Oh, and I'm going to need to get a good KVM switch
Many of us might define "good" as "USB for KB/mouse and digital for video." With that in mind, I bought a "good" KVM last fall for $100. It's a Belkin 4-port SOHO.
Works well enough, no complaints. Full cabling was included for USB, DVI and sound (Line-out + MIC) for all four ports. Nothing else with digital video switching was even within 2X the price at the time.
