As a followup to what Combat said, try eBay. There are a number of sellers from Russia, selling both painted and unpainted 54mm figures, some from the better known studios, and for reasonable prices, eg, less than $20, many for $10. Search in the "Toy Soldiers > Post 1970" category, and you will find many. Even many of the unpainted castings are antiqued, with an India ink wash, and are very nice figurines done in this style.
The only drawback is that shipping might be as much as the figure; I haven't paid close attention to the shipping costs. I just know that there are many figures up for auction, and all at prices well below what AeroArt will charge. Something worth considering.
Prost!
