Wait for flea market season and get one there. You won't have a lot of trouble finding plenty of perfectly good maul bits that might need a little grinding and they're as good as new. Check out the videos on youtube on how to properly hang/grind one.

If you go the flea market route you'll save a good bit of money. I always suggest people who are splitting their own wood have two mauls. One lighter one you'll use 95% of the time and a big 8 pound smasher for the tough pieces.

Good luck.
