I have been looking to pick up the book for awhile but didn't want to spend the astronomical prices they ask whenever one pops up on ebay. I came across the website
http://t206players.com/
and ordered right away. Only took 5 days to get here. Got the book, a nice little letter, a reprint card, and a T206 bookmark for $25..... and the book is signed by the authors. Hard to beat.
I haven't seen any info about this on NET54 so I figured I would post it in case anyone else was still looking to pick up a copy.
Also, I missed it when I ordered mine, but if you put a note in with your order details, they will personalize the signatures for you.
