I hear you. This is prolly the only (formal) Tomato publication I
don't have. I mean I even have all of the IDEA mag stuff, which has been sold out for quite some time. Anyhow, good luck, I've been on the lookout on and off for a few years now as well, to no avail. Ebay and Amazon are useless, as I'm sure you already know, and most booksellers don't really hang on to stuff like this for very long at all. A rarity indeed.
Good luck!
