It was a sales tax free weekend here in Massachusetts, and I went a little silly. I was at the local guitar store and they had a Hercules stand and I was taken with the fact that it has an auto-grab system; the weight of the guitar pulls down the frame on which the neck sits about an inch, and little fingers rotate up, keeping the guitar in place. You have to lift the guitar to release it. Pretty cool.
I spent several minutes just pushing down on the top and watching the little fingers rotate to keep the guitar in place.
Of course, I had to buy one. I already have a guitar stand, but you can always use a second one, right? ;)
