Found a website with lots of O gauge western figures, all cast in lead free peuter, and only about $4 each. Go to the site for Knucklebuster Minatures.
Problem is, they are unpainted. (If only I could paint.)
Other problem is, at least half of them are very uninteresting western women. Cooking, sewing, making bread, etc.
There are some good riders and miners though.
