need monitor low to desk, Help???

Hi,
I need to find how low monitors adjust down to the desk. All the reviews and specs talk about everything else. I have a back injury and at my desk I need the monitor all the way down to the desk (looking up is not an option). Laptops work great. I would like to set up a 3 monitor system. I like the Samsung 206BW but the stand will not let it get low enough. The HPw2007 goes pretty low and I might have to settle for that even though I like the quality of the samsung better. Do I just have to have a custom stand built?. It's a pain going store to store and shoving all the monitors down. If I could find specs on lowest adjustable height to desk would be lots easier.
Would love your feedback.
