I'm trying to decide on a lcd arm for my 20" cinema display. I've narrowed it down to these two. egrotron http://www.ergotron.com/Products/De...t/mid/396/PRDID/1/language/en-US/default.aspx egromart http://www.ergomart.com/LCD_MONITOR_ARMS/IOS7000adjustability.htm I'm leaning toward the egromart arm just becuase I think it looks better, cleaner. But I have a nagging feeling the egrotran arm may be for funcational or practical of a design. Any one have any expierence with arms of either style or just general thoughts on them?
