I'm considering getting an articulated keyboard tray; do you guys have any that you'd suggest? The smaller the better, all I really need is room for a Filco tenkeyless and maybe a small wristpad. On-the-fly adjustable would really be great.. I don't have any good bookmarked sites to look this kind of thing up. My first instinct is to go to somewhere like Staples, but any suggestions would really be welcome.
