This is really only worth the money if it's a corporate party. Having the roller and thre server would add a touch of class to an event. I just sold the idea to my boss, but they are booked. The guy that answeredthe phone was herk too. I will find someone else I'm sure.
Update: The guy at the link is a total jerk, but i have found several other companies that are more than happy to help out. Thanks Google
