For the two models I've done I tried to follow Daz's guidelines which are try to keep it under 30,000 polys. My thought was that if someone, like myself, is going to pay for an item they don't want 200 polys and a cheesy texture that is going to clash with the lighting effect on the figure. The glint on the barrel of the gun should match the highlights on the manical smile :-)) How about putting the polygon count(s) for the model(s) in the product description in the Store? A lot of other model sellers, like viewpoint, do that and you can choose between high and low polys depending on your needs. Texture sizes would also be nice.
