How much did your glasses cost and how much do you love them?

If you could quantify your love for your glasses on a 1 to 10 scale that would be optimal, but I understand if that scale is too rigid for some people. I will then plot your answers on a graph to ascertain what relationship, if any, exists between cost of glasses and how great they are. If I have enough answers to make this graph worthwhile I will link back to it at the end of the thread. (Also your answers will be used to settle a debate between me and someone who is wrong.)
