What's the best sitcom writing class in NYC?

I'm a comedian who wants to start dabbling in other types of writing and was thinking about possibly taking a sitcom writing class on writing a spec script. I don't know where to start though. I know Pit and NYU both offer courses but I want to take the best valued one (they're very different pricewise). What would you recommend? and are there any other good places to take a class like that in NYC.
