Damn dude, that's mighty sexy. I love strategy guides and have recently been pursuing the penny guide hunt. I'm fairly selective with what I'll buy, I'm not going to pick up every guide I come across. I mainly look for rpg guides or guides to "quality" games (like my recent CoD 4 guide). I've probably got about forty or so and I'm already feeling a little overwhelmed with them. Still, I'm sure I'll keep going after them.
And yeah, DoubeJump guides are the best.
