I am looking for some recipes for some dry spice rubs for beef jerky. Any suggestions?

I am going to be putting svereal together in a gift basket for a friend for Christmas and am having trouble finding just dry ones online. Alot of them are more of a marinade, which would be harder to package. Any suggetions for some dry spice rubs for beef jerky or a website or link that may have some for me to put together. I don't want to buy any prepackaged ones, I want to put them together myself. Thanx!
