How to Buy a Zine?

[halotolerant.livejournal.com]

Like many people I have read and seriously loved 'Harlequin Airs' by Ellis Ward, and the gorgeous Susan Lovett illustrations. I bought a copy of 'Dumbo' on impulse just because it reminded me of the circus setting, that's how much I enjoyed it! *g*

I would love to own a hard copy of the original Zine with the illustrations, but the problem is, I've never bought a Zine, I have no idea how to (or how much it would reasonably cost) and what sites are reliable (I've seen commentary before about certain existing sites being out of action, except I cannot now remember which were mentioned). Can you even get this story anymore or is it really hard to find due to popularity?

Advice very much appreciated *g*
