Phillip,
Check out Alex's photo gallery, he has several examples of that pen style in different woods. One of Alex's favorites is cross grain Morado. It's difficult to turn and keep round but the finished product is outstanding due to the color variation in the grain.
You can pick up a small board at Klingspore and cut your own blanks.
Also, the "starter kit" from PSI is a good deal with the bushings and barrel trimmer sleeve included however the drill bits they include are throw away items.
