I am with Catherine on this, I think that if guys are only really comfortable with the more well known ladies, less and less ladies will enter the supply side, and the demand side will likely be concentrated more on a smaller number of ladies, and voila, prices may go up. Today, it is so easy to enter, advertise and draw attention, that the supply side grows easily. So, today we are likely facing the lower end of pricing, and likely to see things go up.
I am a frugal (read cheap) as any guy, so I do look out for the bargains, attempting to wade through and find the gems. Right now, you can get great value, many lovely ladies out there.
