I have an autographed copy of the first edition that I'll treasure forever (or until I think I can make a fortune on eBay), but don't make the mistake of buying one of those. You want the shiny new edition that's not actually going to ship for a few months.
Pre-order two... and you'll get free Super Saver shipping from Amazon! Pre-order nine, and you can supply the U.S. Supreme Court. Some of them could use a little diverting reading material now and then.
