Does anyone know of a ganga deal on a ATX PSU?

First of all, pardon the title. I was typing my question and not able to get it to post. First time I tried "test" wouldn't you know it posted.

Anyway, the title really is "Does anyone know of a ganga deal on a ATX PSU" Should be 600W or better and have 12-V and 2x12 connectors. Used or refurbished is fine.

Thanks!
