Its worth it to me. If you look at the age group average as to who attends a Paul show, its not the teenage population. The majority of the crowd falls into the adult category and $250.00 isnt out of the realm of spending for them. In another words, most of the crowd is older and already established.
I would think $250.00 is an average for the big time shows (although I dont know who would fall into this group), but I paid the same for a good seat for Elton John a few years ago. I'll probably pay the same for the Stones this time around too. If your not comfortable with the prices, dont go.
