I've had good luck buying on eBay, just make sure you get free shipping. I might also try the Maxis Zillas or ITP Mudlites. In Maine and maybe NH, you might try "Uncle Henrys" swap it magazine or website. I got 4 new 14" Mudzillas on new aluminum rims for $400 a few years ago, off Uncle Henrys 3 years ago.
