LCD arm/stand thoughts?

I'm looking into getting two new LCDs (ViewSonic VP2030B). I plan on buying an arm to attach to them for easier range of motion. I've been looking around and have basically found three options, as described below:

1) Two Ergotron LX Wall mount arms.
2) One Ergotron LX Desk mount arm with an additional arm (saw something on eBay about possibly doing this).
3) One MOView MV2XDC dual arm.

According to Ergotron's site, the ViewSonic VP2030B weighs 11.5lbs without the stand.
So I have some questions. For option 2, will I be able to mount an additional arm to the pole and will the single pole be able to support two LCDs? For option 3, would the MOView arms be strong enough to support the LCDs I want (is 2.5lbs below the weight limit too close)?

I'd like to get the MOView because it's the cheapest option, and exactly what I want. I don't want my dual displays fixed, I want to be able to move them however I like (have two vertical for long articles, or maybe two horizontally, like normal configurations).

If anyone has any of these products, please let me know how they stand up, and what would be best. Thank you very much.
