If you've got a few (or more) guitars, my favorite stands are from K&M. This one is the 17513 which holds three guitars and they also make the 17515 that holds five. You can get them from Guitar Center/Musician's Friend and other places. The soft translucent plastic is the safest for nitrocellulose finishes but you can also get them in all black.
There's also a company called Take A Stand (http://www.takeastandinc.com) that makes beautiful (albeit pretty expensive) stands. Many of the luthiers I saw at Healdsburg this year were using them to display their guitars. Each one is custom made with your choice of wood, inlays or bindings, etc. Here's an example
