I picked up a pair of stands at Compusa over the weekend for $35. They're easy to assemble, pretty sturdy, and work well with the E30's. If you'd like, I can get the exact brand/model and post them here.
On a related note, I also was able to buy a pair of the E30's for $120 at Compusa. They sound good and fit in nicely with my current home theater setup.
