BOOYA! Best $35 I've spent in a long time (since I had the small monitor on the left laying around)!
Bought a Diamond "USB Display Adapter Pro", hooked it up, downloaded the Mac driver off the interwebz and voila!
The funniest part about this though is that I was running 3 Mac displays back in about 1988 on my Mac II with 3 video cards in it. Back then the average person couldn't even wrap their head around TWO monitors let alone 3. It's like I've come full circle.
