Dr who is a very under-rated game, there is a hell of a lot more to this pin besides smashing up daleks( although this is a hell of a lot of fun!
I love mine but as I like to flip and move my pins pretty reguarly it will more than likely be up for sale soon.
Hint Hint for sale 
I have a small collection and I like to change them up, so i'm always open to the idea of a sale or trade.
Having said that Dr who comes up pretty often for sale, so there should be a few out there to choose from at a good price in the current market.
