James put the Weird Fantasy Role-Playing Deluxe Edition - Rules Book, The Magic Book, The Referee Book and the Tutorial Book up on RPGNow - $12.50 for the lot of it. The Referee Book might be worth that on its own, its just that good.
485 pages of gaming fun, including character sheet, an info sheet and Raggi's Recommended Readings
(short review of the Referee Book here.)
Some might prefer a free peek, and James is doing you one better... he's offering the Rules Book and Magic Book as a free download on his website. They are art free but the real deal.
I think it's awesome that you can get everything that was offered in the collectors box for less then $23 total in PDF (if you add in Tower of the Stargazer and Weird New World, reviews here and here).
Give Weird Fantasy a free grab if nothing else. It's good, well written, and making me think of house rules and adding classes - that's amazing unto itself ;)
