I voted "less than 5.00", but I view that not as a cash payment, but more as buying the DM's snacks and drinks, chipping in for group supplies, and so on. In reality, I'm usually the DM, and while I'd love to be paid for my efforts (and would be able to devote much more time and energy to the game if I were), I enjoy the time I spend doing it enough that it's not a burden. Plus which, if I were to try to charge enough to make any sort of decent hourly rate, it would be far more than any players would be willing to pay. That said, I did once take $120 to run a game at a convention, but that was for a group of out of town players desperate to get another game in, and required that I run from midnight to 4AM rather than going home and sleeping, so there's no way I would have done it without the money. It ended up being a pretty bad game because of the combination of fatigue and running the module cold, but it was enough money to be worth it just treating it as work.
