VESA mount for dual monitors, rotatable portrait and landscape?

Hey all,

I'm looking for a specific monitor setup. What I want to do is take two 24" or 23" widescreen monitors (1920x1080) and have them side-by-side, both rotated 90 degrees, so the screens are tall instead of wide.

But, the part that makes it a bit tougher is that I will be using one of the monitors with my Xbox at times, and I would like to be able to rotate the monitor back to its normal widescreen state with ease when this happens.

Can anybody recommend a good VESA mount for this sort of thing? I've seen several VESA dual-monitor mounts that allow 90 degree rotation in portrait mode, but I haven't really had much exposure to VESA mounts in person and I'm not sure what I might get. My worry is one that rotates but the act of rotating it will be difficult to perform for some reason or another. If the two monitors are side by side vertically, you'd think you'd also have to move the monitors apart a bit to rotate the one monitor to its normal state. I'm concerned that I'll pick a mount that doesn't handle that very well and it will take a lot of work every time I use the monitor on my xbox. Any input from you guys would really help.

I'm trying to keep the cost to a minimum, but I understand a pair of widescreen monitors with a VESA mount is going to put a hole in my pocket no matter how I do it.

If you can recommend any good 23 or 24" widescreen monitors with 90 degree rotation and HDMI without the VESA mount, go ahead. I'm leaning towards the mount but I am all ears, especially since not having to buy the mount would save me money.
