dumb enough to pay = deserves it. but on the other side, they are not in production anymore and were part of a limited production guitar model. so they're bound to become more expensive as time goes by. but that's not now surely.
The co-owner of the guitar store I go to said HM's in general would go up in price now that they've hit 20 years old. I think we're seeing some of that, but you're right - $50 & $100 for knobs - it's too soon for that!
