Actually, I went on a helicopter tour of NY, cost me more than US$150.
I have seen many tours in my travels around this planet, many at US$150+.
If you can't afford it, fine, but don't put it down and show your ignorance by really not knowing anything about tours that offer a great ROI (Return on Investment)
As we have stated, this is not for everyone, but going by the response we have received, people are interested, will be going on the tour and appreciate this level of tour.
2 mins on Google pulled up the following:
Paris - US$200
