I have a question for those that currently have these devices. I am thinking about getting one, just not sure if I want the 2 or the 4. I currently have 2 19" monitors on my main comp, plus another 19 widescreen on a seconday computer. I am hoping to upgrade to 22" at some point. However, i notice that while the smaller one says it can handle up to 22" monitors the 4 monitor one only says 19". Is this just because of size? or is weight going to be an issue?

@HERC130: Nice setup there. What do you use to hold the monitor above your primary center one? The one you use for videos when raiding? I can see where the 2 - 4 monitor ones are, but can't really tell what is holding that guy up.
