I have found it is the same with photography equipment. I have had people tell me that their little point and shoot camera can do the same as my Canon kit for a much lesser price. Uh, okay. I have my reasons for getting the expensive lenses and body, just as I have my reasons for getting an expensive (to those who don't know) bike.
But I tend to agree that people who ask how much my bike or my camera cost are being rude. I'll usually tell them that it was more than what my truck is worth.
