What to get...

My parents sent me a gift card from Amazon.com for my birthday.  Now I've gotta decide what to buy.

In my Wish List, I've got a few books I'd like to pick up, but which one to get?

Northern Hero Legends by Otto Jiriczek, apparently a POD facimile of an out of print, now public domain book that I can't find anywhere for a free download (the original German might be available, but I don't speak or read German).

Tros of Samothrace by Talbot Mundy, some Appendix N goodness.

The Voyage of the Space Beagle by A.E. Van Vogt, some Star Frontiers recommended reading goodness (and apparently the inspiration for displacer beasts and the Alien).

There are a few other things I also wouldn't mind getting, but those are the top three.
