I know this is quite a frequent question, as to why certain razors are 'hot' or fantastically expensive like the Filly 14s and Wade and Butchers. I know that there are trends and things go in and out, but what I'm wondering is what really drives the trends, and I know this is something that really can't be answered by conjecture.

So, people who love / want / have any of the popular razors that often command high prices, why do you desire them? Perceived steel quality? The ability to have a rare (or perceived rare) item? Showing off? Keeping up with the neighbors? Belonging to a cool club? You just really like them? Possible associated history (as in the 'for barbers use' razors)? I'm very curious to hear your motives / opinions.
