I'm sure this has been discussed here before but for the life of me I can't find it. What does a guy need to start to turn some pens/pencils?

1) Obviously a mandrel for my lathe.
2) Drill bit for blanks and tubes.
3) Wood I have some nice 5/4 curly Maple and Walnut burl scraps lying about.
4) ???
What else would I need? Are the supplies/pen parts different sizes between suppliers or are they pretty standard?

The Mrs has been asking what I want for Christmas and I'm trying to give her some ideas. We can't get crazy with funds and I thought about this and/or maybe a BB bowl gouge or 2.
