Extra monitors - external options

[Renovatio]

First of all, I'd like to thank everyone who helped me out on my laptop choosing thread. I haven't decided, but I'm definitely not going Mac this time, not yet at least. If anyone has any more insights, I'd definitely appreciate them, but I'm definitely leaning towards something with the Sager N5793 configuration.

I wanted to inquire about two external options I found for connecting extra monitors to your system, the Villagetronic VTbook and the Matrox Dualhead2go. These seem interesting enough, but do they work well?

Thanks

Don't forget the EVGA UV+ for additional external monitor support. I have nothing to add on this, but I am interested as well. I have a 17" MBP I would love to get dual 24" 1920x1200 screens working.

It seems the VTBook one is the only one that provides additional graphics acceleration. The UV+ and Dual/Triple-head2go both depend on your graphics card.

Are there any others? Especially any that might give you additional juice to run the monitors on?
