I'm also on the lookout for reasonably priced copies of Gary Gygax's Dangerous Journeys books. I keep hearing, from sources whom I generally trust, that there's a lot of good stuff to be found in this game and its supplements. I'll admit to being skeptical, as I'd looked at them briefly during the 90s when they were released and saw what looked like an unnecessarily complex game that used an invented vocabulary to describe many of its basic concepts -- two things that didn't interest me in the slightest, despite Gary's name on the cover.
But, like a lot of things, I'm prepared to re-evaluate my opinion on the matter. I just need to get hold of the books to do so and they seem strangely scarce and/or expensive through the usual methods I employ to find out of print gaming products. So, if anyone has any leads on these books at reasonable price, please do let me know.
