Interesting question. I would do it only if she's the absolute perfect type for my taste... But that's the catch. For me to know that the girl was my perfect type, I need to have seen her before.
Through out my punting days and nights I've fucked so many girls, but there are those that stay forever in my mind because they were the most desirable, but they are all gone... All are no longer working.
So the real answer to the question is, I will NOT pay $1500 for a girl I've never seen, but I would gladly pay even more than that just to be able to fuck one of my all time greats one more time!
