I'm interested in a monitor arm (desk mount) for a 23" apple display I plan to purchase. I'm not sure if I want a radial arm or articulating arm - I think radial will give me more length extension, if so that's what I want. There are so many choices out there, it's hard to know what's any good. I have an anthro console unit desk and I need for the monitor to extend at a max of 22-25 inches (I have poor vision so I need the max expansion). So far this one is on my list as it expands up to 27" http://www.ergomart.com/HD_LCD_monitor_arms/lcd_monitor_arm_SAA2718details.htm Any one else use this arm and/or are there any other recommendations from those who have similar arms?
