Depends on what you want to do with it. If you want it soft, wallhanger or if you want to mount it. What I'd recommend is to contact a taxidermist and have him/her order you the McKenzie Home Tanning kit. It's like $25 - $30 and has a video and most of the chemicals.
I've had good luck with Protan. Minnesota Trapline Products and the Snareshop both carry it. Will give you a nice pliable pelt if you break it nicely. An oil to work into the hide as you break it is highly recommneded. Go to taxidermy.net and spend a few hours reading the posts on tanning.
