Wow. Simply "wow!"
This year's Frog God Holiday Grab Bag was full of Swords & Wizardry goodness. With the exception of the core Razor Coast book, I don't think any are dupes of what I currently own (and one of the three D20 releases included was Caverns of Tracia.
Now, each grab bag is different, so if you order one expect your contents to be different. Mine were divine ;)
