Especially if you want it stable enough for panoramas, you'll have a very hard time finding anything for fifteen dollars. Exchange rates and all. You might get lucky on Ebay (tripods are expensive to ship, though,) or at a yard sale.
Back when VHS camcorders were in use by home video hobbyists, though, there were made a number of rather big and clunky tripods for them: they used to appear at yard sales and flea markets (and even curbsides) fairly often, a number of years ago. It's possible in time you might find one. Now that video cameras are palm-sized, there isn't so much call for the big things among consumers: as the things got smaller, people tended to consider the big cheap tripods unnecessary and in the way.
It'd just be a matter of luck, though. It's possible something might turn up on Craigslist, though, or someone here might happen to have something they don't need.
You'll probably end up spending a fair bit more, though, in all honesty, at least if you want it soon.
If you get a choice, remember that simple and heavy is best for your photos, if you're going cheap.
