I get the question about my Bike Friday because people are genuinely interested. So I tell them that there are different models at different prices. Then I give them the website. If I tell them how much mine cost, the focus shifts to the price and the fact that I paid it (OMG, you paid that much for a bike??!!), not the bike. I want the focus to be on the bike--if they are really interested, they can determine what model they can afford. It has nothing to do with my bike at that point.
