Sable, as per usual, has it right. When I started in this hobby, I hunted what was rare. Some of it I really do enjoy, so I'm glad that I went to the trouble, but I also admit that some of it I wanted to try - and to "have" - because it was rare and I thought it would be "cool" to have a stash of the "good stuff" that was hard to find. The old adage, however is true, you cannot have your cake and eat it too, so once you have the rare stuff, you may find that you sit on those tins, knowing that replacing them could be impossible, or at least, very expensive and/or time-consuming.
For example, I'm still wondering what fortuitous circumstance will lead me to crack open that old tin of Three Nuns.... or will I die knowing I "had it?" Boy, that sounds grim - not my intention : )
It can be fun to find something rare and pay a fair price for it, or even sometimes to overpay to have a unique experience, but it is far wiser to invest the time to try a lot of blends that you can easily find and determine your tastes and preferences first. With that approach, you can establish a cellar for which you can a) pay a fair price, b) add to and replace tins over time, and c) base any splurges on rarities upon your well-established tastes.
PS - I will say, in my defense, that I didn't pay obscene prices, I just invested the time to hunt.
