This is worth adding to the discussion. I've shown this book here before, but since it was a few years ago our more recently arrived contributors may not have seen it. I'd been looking for a copy of JIM #1 and despairing over ever being able to find a copy I could afford, then this one popped up on Comiclink and I was able to get it for under $600. While it is a 0.5, it is complete and I doubt you would ever find a nicer looking copy for the technical grade. While I no longer own it, it is only because I have since upgraded and traded it as part of the deal. The moral of the story is to not completely give up hope on books you think may be out of your price range, the comic gods will sometimes surprise you in the nicest ways.
