Every time I'd walk into a National Bookstore or Powerbooks I'd see the hardbound edition and briefly consider it, with my conscience nagging me from both ends. It's just 800 pesos, but still... it's 800 pesos.
It has always ends up with me reasoning that it'll be a long time before I've run out of new things to buy and started buying slightly different versions of things I already have.
This rule goes out the window when I see a second-hand-but-good-as-new copy for 200 pesos.
Ahh.... that's much better.
