What is the highest you would pay for a concert ticket???

i know there is lots of cd or dvd which is unexpensive. but i did pay a cticket for 400 rmb when the singer named Jacky Cheung came to city where we live.the songs are good .it has powerful message and rhythm which just move me.there is a lots of people there and all of them were craze.but it is not worthing paying for it because of having no position for me to see the singer nearly.
