I'm not sure if this counts, if not, I apologize mods. I need a keyboard tray because my desk that my dad built me many moons ago for my 10th or so bday does not have a keyboard drawer/tray, and I have terrible carpal tunnel + tendonitis. The desk is solid wood, but it does already have a drawer in the keyboard region, and this drawer is constructed of fairly thin wood. I want a keyboard tray that I can attach to the underside of this drawer, but I'm not sure how good of an idea that is with it being fairly thin wood? The tray cannot be too heavy or I suspect it the wood will not support it. I also want a tray that can fit both mouse and keyboard, all in one, NOT with the mouse off to the side on a separate little piece, but one long rectangle. Otherwise, I'm not looking for anything fancy (though aluminum to match my mac pro would be very pretty!). I would prefer not to spend more than $50. Thoughts, suggestions? Thanks!
