I know you have to pay for your web hosting, but the SpywareBlaster database is just a few 300 KB files. I think it is a little too expensive charging $10 for a year of AutoUpdates. However, I have an idea. You should just get people to mirror the update files. For example, if you want, I'll make an empty sub-account on my Comcast account, enable Personal Web Pages, and give you the username and password so you can upload the database to it. Comcast PWP doesn't have a bandwidth limit, and you don't have to pay extra for it. This would lessen the cost of your web hosting, and allow you to make AutoUpdate free, etc.
