I do not think Leica buyers consider any price to be an issue. For many, it's difficult to grasp, but at a premium pricing, the clientel they are going for is absolutely diffrent from a normal consumer. They flat out don't think about money same way others do.
I actually know a friend who got a Leica M8 and 35 Summilux for 3700 euros from an old lady, who got the camera for holiday pictures. She the proceedeed to buy Oly E-P3. I'm not kidding.
Anyway, i guess Leica is something that Apple was about 5-7 years ago. Unique. You buy it, beacause it's one of a kind, and everyone knows it's premium.
