You might check with your local mental health organization. Our community counseling center has an outreach office called Mountain House, and they have full-spectrum lights that anyone can walk in and use. Yes, we live in an uber-rich resort community, so my idea of normal is skewed, but it wouldn't hurt to check and see if you can "borrow" a light instead of having to buy! You also might advertise on Craigslist or somewhere that you need one, and someone might give it to you for cheap or free.
