It looks like Maxwell beat me to the punch, as he chose the Heartwork Bravo Pedestal as his Daily Find pick for today. I had their No. 1 Monitor Stand bookmarked for both it's simple design and function, handy for anyone docking their laptop to an external monitor or use with a Mac mini or similarly mini-sized desktop. You also get the bonus of elevating your screen a few inches, helpful if you're a taller user who would benefit from improved ergonomics and line of sight with the screen...
No.1 Monitor Stand came about because Heartwork's first client was frustrated with imported monitor stands that had a lot of extra parts detracting from what he felt should be a simple, straightforward design. Insprired by Donald Judd, No.1 Monitor Stand is made in the USA from one piece of bent, 11 gauge steel powder-coated in matte white. Looks equally good with Macs and PCs. This stand raises monitors to a comfortable viewing height to help prevent neck strain. Stow laptops underneath for in-office use or extra desktop space. Equal parts simple, elegant, and functional. 17"L x 9"W x 5"H. $45.00
We always love to give a DIY option for those inclined to skip the off-the-shelf solution. Here's a reminder about a DIY Rolling Monitor Stand designed to make carting around an iMac across a shared desk a whole lot easier.
It's not necessarily a monitor stand, but you could possibly cut the back of the IKEA BOALT to hide away a USB hub, router, or other peripherals from view while elevating your screen.
