Have you tried any of the Multnomah libraries? They loan out more than just books. They can give you tv's, vcrs, and radios even. I don't think you can take them out on a loan, but they do have them onsite at every library and you can just go into thier media department and use them at the library. (If you're watching a movie, they usually make you bring headphones).
They have so much stuff. You should go into your local Multnomah library and ask if they have one. If they don't, I can almost garuntee you that the central library downtown will. That place has everything!
I know it might be out of the way for you to go to a library, but it's the best thing I can think of.
