I've only tanned a skunk hide, but the Rittel's EZ kit works pretty good. You do the whole soaking and rinsing stuff, but its not too bad. The acid is a safety acid so you can dispose of it easily. The hardest part is fleshing and thinning the hide. The thinner you get the hide, the softer it will be when done. I ended up with some holes in the skunk I did, but it turned out pretty good for a first time thing.
I've got a couple of deer hides and brains in the freezer, but I can't ever get around to getting started on them.
Good luck.
