The thing is that just because you're paying more money doesn't mean the service you get will be any better. OK sure, there are plenty of skanky £50/hr Romanians who will not surprisingly give you shit service, so a definite case of 'you get what you pay for' there. BUT - some of the best reviewed girls on here are in the £100-£150/hour range, they're hot, and they provide great service. Some of my best punts have been with £100 or £120/hour girls, that were both hot and provided great service.
Can't say I blame you - I went through a phase of going for what I thought would be 'better' punts by picking the real stunners. But for me anyway, if the service isn't there (which with the couple of 'elite' escorts I went with, it wasn't), it feels like a waste of money. Also, I found that the 'elite' end of the market is just as prone to B&S as the cheaper end. Maybe that's not true if you get up into the £1,000/hour range - maybe then you DO get someone who looks like Salma Hayek or Kelly Brooke or whoever. I will never find that out first-hand as I don't have that sort of money to splash around. But I don't think that looks-wise, there's any guarantee of a stunning girl at £300/hour compared to £150/hour.
