Where should I post scuba gear for sale? Good sites?

I tried to look up some SCUBA websites, but they didn't seem to have "used gear for sale" sections. So, maybe try craigslist.com?

There's the obvious ebay.....

Thanks to both of you for your replies

I was hoping that maybe someone on this great big resource might already have a bunch of links together and that it would save me the work to search for it. My intent isn't for people to go out of their way doing my own research for me.

Thanks again.
