I'm considering mounting my 3 LCD monitors on either an Ergotron DS100 Triple-Monitor Desk Stand seen here http://www.ergotron.com/ConsumerPro.../55/ctl/Product/mid/386/PRDID/16/Default.aspx or on 3 Ergotron LX Desk Mount LCD Arms as seen here http://www.ergotron.com/ConsumerPro.../55/ctl/Product/mid/386/PRDID/1/Default.aspx. I prefer the LCD arms because it lifts the monitors off my desk, but I am concerned about the sturdiness of the LCD arms and the monitors staying in place. I don't plan to move them much. The price for these are about $190 for the desk stand and about $375 for 3 LCD arms. Does anyone have thoughts on these two monitor configurations? Thanks.
