Can two external displays be driven from one Thunderbolt port? I have the new MacBook Air which only has a Thunderbolt output (no HDMI or DVI) and I have 2 external monitors. How can I get this all hooked up (at the lowest cost, if possible)?

EDIT:
After using the DualHead2Go ME, I'm half-satisfied; it does split my single external port into 2 DVIs, but the externals act as 1 with double the width, so the resolution is very off and weird to look at. Looking back I probably should have bought the Pro to support both of my externals, but with my current Air this is the best I can do for 2 externals.
While Apple's display adapters will let you connect one of these external monitors, there's also the Matrox DualHead2Go Digital ME which will connect two external DVI displays (I've never seen or used one, ymmv).
