If you live in Mpls/St. Paul, try going here for wargaming supplies: Hub Hobby Center
They're a huge hobby shop in Richfield, and though their website doesn't reflect it, they have an immense amount of plastic wargaming-useful models in all different scales and eras for really reasonable prices. They've also got paints and modeling supplies for figures and terrain. Truly excellent. Go now.
