I've been getting my Dell 3007 set up and one issue to solve is the lack of inputs. my 2405 had five, this monitor has one but i prefer to use two.
Enter the Belkin Flip DVI-D
Its a KVM switch with built in cables. It'll take dual link dvi signals, usb keyboard and mouse, and audio from two machines and allow you to smoothly switch between the two. I have mine hooked up to my MacBook Pro and MacMini. Works perfectly, what else is there to say?
Oh, and the deal - I got it on eBay for $75 and picked it up locally. Goes for $125 on amazon which is still cheap.
