Mixing business with pleasure Part II

Would you or do you date co-coworkers?

I had an awful experience a few years ago and swore I would never again date a guy I worked with.

But there is this one guy I keep running into. I've seen him out a few times, but aside from a wave, avoided any social interaction. We work in different departments, but my office has contact with all of the divisions across the organization. So every now and then I find myself working with him for a month at a time.

Is he worth pursuing? Or should I stick with my current policy and wait for the day he finds a new job elsewhere to make my move?
