I'd keep looking in my spare time. Why quit before you have something else lined up? I'd have to evaluate why it was bad, how bad it was, and how well I could mitigate the problem(s) when determining if I wanted to look for another job. It would have to be fairly bad for me not to give it at least a month - more than just me thinking it wasn't quite as cool as I thought it would be. I don't see how it would hurt your record if you found another job and left within a month - you could just leave that one job off your resume.
