I ran into the same problem when I was looking for a stand. They were either way too flimsy or cost way too much, so I built my own. I bought a fairly cheap circular saw for like $70 at Lowes and then bought the lumber. All told, I probably have $100 in it total, if that. Not to mention that it's a lot sturdier than what I could find.
It may not be as pretty, but it definitely does the job.
