Have you been contemplating ordering up some script coverage? If so, then you know that it can be a pricey little service. So, is it a necessary service? If so, when do you need it?
I think if you can find a place that has a reputation of offering quality script coverage, then it is worth it. But it is only worth it if you have a script that you think it as polished as possible. That way you are sending out your very best. And in return you will get a pro’s opinion. Just remember, that at it’s core it is still just an opinion.
