I read a few different reviews of the DS100 triple and quad stands that concluded the same thing you did Micah. The LX series is supposed to help solve some of the setup/config problems but on the flip side cost a little more.

I ordered the Ergotron LX Triple Display Lift Stand last week and it arrived on Saturday. Putting it together out of the box took about 2 minutes and couldn't have been easier. I'm waiting for two LCD's to arrive today so that I can actually put the thing to use. I'll post a screenshot and final comments once i've gotten things all setup and working tonight.
