I don't own a single pre-war card that isn't part of a set or run. It's all about the challenge of completion for me. My brain can't wrap itself around collecting individual cards willy-nilly.

The one piece of advice I like to give is to buy the biggest card first. Then once you have all the HOFers, decide if you want to complete it with the commons. If the answer is yes, the rest will be pretty cheap to do, relatively. And if the answer is no, then selling HOFers is way easier and even potentially lucrative. It's temping to want to start with a big group of commons in order to feel accomplished right out of the gate, but it never ends well for your wallet.
