This price is not surprising. Tour issue Camerons go for a lot of money. They are obviously worth it to the people who collect them.
It's nothing to do with how good a putter they may or may not be. The people who buy these particular models rarely if ever use them.
Probably best to let people spend their many as they see fit.
My personal view is that it seems to be a little immature to collect things that say "Tour Use Only" and such stamped and embroidered all over them, but I can certainly see the attraction of a lot of the 009 putters.
We are not talking about a mass produced OTR Cameron here.
