Well, certainly an interesting topic!
I don't think I've played one long enough to comment on the long-term keeper status, but to me it is a good enough title that is instantly recognisable. If money was no object then I would be buying a good clean example for a decent price (that way if you do get bored with it you can sell it on at what you bought it for at worst).
Given that money is an object for me I would rather be buying two or three pins for the same final sum.
