Working from home position

I’ve been contacted by a headhunter for a position that is in my IS specialty, and I would work from home. It’s a contract position, which I’m not terribly excited about, but the appeal is working from home. I work from home from time to time in my current position, and I like it. If you have worked from home on a regular basis, or are doing it now, what are the pros and cons? If you had a chance to do it again, would you take the work from home position?

Thanks!
