How to find a babysitter?

It's harder than you might think! Really!

Unfortunately, I don't have relatives here that I can entrust my child to (and after hearing some mom's stories, would I really want to?) And, of the other mother's I know (there aren't many. We've been here over a year, and I don't know many people. Sad.) they either don't have children of babysittable ages, or, they don't use a babysitter because they have the aforementioned relatives (or for other reasons.) So, asking other mother's about their babysitters, just does not work for me.

I've been watching the ads from Craig's List, and, well, hopefully a couple of prospects will work out well.

Any suggestions? How else does people find babysitters?
