Best Way To Add Extra Monitor?

[rjupiter]

yeah, i have a Asus G73JH with a ViewSonic VP2365wb plugged into my HDMI port. I want to add another of the same ViewSonic but like most laptops you can only have any two monitors running at the same time. i have been trying to find a workaround and have looked at the Aluratek USB Hi-Res 1920 x 1080 Adapter , ENCORE External USB Video Adapter 1920x1080 and the matrox DualHead2Go and just not sure what i should get or what i should be looking for. anyone have experience with these products or with adding a three working monitor to a laptop setup and can give direction?

thanks

Matrox is probably the best, they have been around for the longest.
