Selling my PRO monitor arm. It's been great on my sled. Attaches and detaches easily, and is 100% rock solid - unlike some other older monitor arms.
Condition is good - a few scuffs in the anodizing where you'd expect, but nothing out of the ordinary. Has a different knob - a winged one, rather than the round one from PRO. I found it locked on more solidly.
I'll get some good pictures of mine tomorrow. For now, here it is on PRO's website: http://www.gpiprosys...onitor-arms.php
