Desk Mount/Arm Recommendations for 27" iMac?

Anyone got any suggestions for a suitable desk mount, or articulated arm with plenty of clearance from the wall, and desk?

I did buy the Vesa mount, and a suitable wall mount, but sadly the wall is almost 100 years old, and to my horror is too soft to support the weight of the 27" iMac.

I think that you need this adapter to work with a VESA mount (works with certain model iMac's):

VESA Mount Adapter Kit for iMac and*LED Cinema*or Apple*Thunderbolt Display - Apple Store (U.S.)

Here are a some products the Apple Store sells:

Sanus Swivel Column Clamp Mount VMD2-B1 - Apple Store (U.S.)
Bretford MobilePro Desk Mount Combo - Apple Store (U.S.)
Ergotron MX Desk Mount LCD Arm - Apple Store (U.S.)
Bretford MobilePro Desk Mount - Apple Store (U.S.)

Thanks my friend I already have the Vesa mount. I have just been reading about the Freedom Arm, looks like it may do the job I'm looking for.
