I use a basic kvm switch for usb right now but I want to upgrade very soon to a full dvi version so I can stop pressing 3-4 buttons to switch from my MBP to PC. I want to purchase a decent one but I've seen mixed reviews on the dvi switchers. I would like to keep the price under $250. Any help would be great! I use a Samsung T260HD display, Razer Lycosa, and Logitech G9.
