I have the TripleHead2Go. It works, but I wouldn't rate it as "works fine".
The driver it came with didn't work (at all). So I had to download a new program. That one works, but it won't remember it's settings. So every time the computer sleeps or turns off the displays or anything, you have to quit the Matrox PowerDesk app, restart it, re-auto-find the attached displays, and reapply the settings.
And then it asks you to reboot so it can remember it's settings.
Also, it sometimes has a bit of noise on the monitors.
It works, and I love having the Macbook Pro's 15" plus two 23" worth of desktop real estate, but I'm not sure it's worth the 300 bucks.
