Not really relevant. I own many things that cost more than the book but I can't really sneak the book into the budget right now either. I could force it into the budget but I don't generally do my purchasing that way. Of course, I'm not tossing around negative comments about something I haven't seen either. He should know better than that. I think if you own two airplanes it's a bit disingenous to suggest that you couldn't afford a $475 book. I appreciate that the book is expensive.
