recommendation for an adjustible wall mount for 30" screens?

Hey there-

I have looked at a few online, but I am wondering if any of you compadres have experienced total wall-mounted happiness?

I will need either 2 mounts that can work side-by-side, or else one double mount that keeps each screen's angle separately adjustible, and I seek lots of up and down adjustibility (because I like to work standing and sitting, though supposedly I'll be getting a high chair - but I am not certain it'll work for me yet)...

Ease-of-motion would be nice too, but range of motion is most important... And strength, I think each monitor is 25 lbs.

If you have one you love that I should check out - or one that you despise so I know to avoid it - please let me know!

Thanks,

M A R L A
