Pirate is a great place for info. You gotta tread REAL lightly there- those folks are ROUGH- but the knowledge of hard core action and general vehicle functionality is incredible. The fabrication abilities of some of the members is pretty amazing as well.
If I'm real straight, I take a lot of stuff on Expo with a grain of salt (not referring to the referenced article in this case, though). More often than not, it's about how much you spend, not necessarily what you've done. Scott Brady and some of the other folks are very knowledgeable and have done a huge amount in their lives, but again, some of it is a bit ridiculous for those of more realistic means.
