Have you checked your local library? Some of the libraries here have DVDs of all sorts and you can check them out for free. Then you could try it before you bought it.
not free, but i think i paid a whopping $10 for mine. You might be able to craigslist it or find something really similar ondemand. Not sure what you have available to you. A nice bumpie might also be able to send you their copy for a bit..
