Took me a while to find a decent hardcover at a decent price, but I think I found one. Not sure the wife is going to like me sitting in the chair reading for hours on end again, but so be it :)
Nobody said gaining the knowledge of the universe doesn't have it's pitfalls. ;O)
BTW Mine's a soft cover that cost $5.95 at the time. I've had it for a bit over 40 years.
