Welcome to NA!
As for what you should buy, get what you want. Buy what you'll play. If you decide to go for a full set, then get the rarer stuff, but like Gloves said, a full set is no joke. That takes a TON of time, space, and money. You have to be sure you want to do that, or you'll burn out and bail. That's not necessarily the worst thing, but it's something that could potentially be avoided with careful thought. Just my two cents.

To the Finder...
The Isle of Koholint is but an illusion...
Human, monster, sea, sky...
A scene on the lid of a sleeper's eye...
Awake the dreamer, and Koholint will vanish much like a bubble on a needle...
Cast-away, you should know the Truth!
