I've been looking for a nice portable miter saw stand for a while and I just received the Home Depot circular for this weekend. They have the Ridgid Miter Saw Utility Vehicle on sale for $99. I picked it up and it is great. The mounting area is huge compaired to others I've seen and my Porter Cable 10" fits very securely.
I have no relation to HD, just like to pass the savings on to others.
