I moved quick on this one just in case. A reader here e-mailed me about a hobby shop he purchased one at and that they had a few left. It would of involved calling them and making a deal, but that reminded me a lot of shops have eBay stores so I checked there first and located a couple easily (several shops had them but they seem to be selling fast as the place I bought from had only 6 left). I got 2 just for the heck of it and wouldn't be surprised if the value starts rising once everyplace sells out.
By the way I'm talking about the HO catalog. The N&Z doesn't seem to be moving quite as fast (our hobby shop did still have a stack of those and more are listed at eBay) but they might also start to disappear as word gets out about the HO catalog.
As for the leatherbound edition, that's what I heard. Could of been a rumor but don't know for sure. Does sound over the top for a hobby catalog yet I did see a "bound hardcover" edition in the eBay listings. It's hard to tell if it's leather (color is black) as the description doesn't specify (maybe simulated leather?). Starting price was $24.99 or "buy it now" for $29.99 (or close to that anyway). From what I can gather all these versions are signed by Phil Walthers for what that's worth.
