I hadn't seen any copy cheaper than $70 in the past year or so. Today I looked on Amazon and just ordered one for $38. Still not cheap, but considered it's an out-of-print book, I think it was reasonable.
I've read so much on this Forum about this book that I can't wait to try something from the real book (What I tried a few years ago, using fragments found online, wasn't successful).
Any recommendation from where to start?
