Connie, I would not worry about disapointing customers given the quality of work you have demonstrated. My advise is model what you want to because you want to and make it available  to others either free or at an affordable price, but make sure you don't put ego into how many sales or how much money result. Then any sales and any income is an unexpected treat.

I think Poser is a valume versus per-unit market... you can rack up a hell of a lot of $5 sales to be honest and if your attitude is that you don't intend to quit your day job just treat any income you get from sales a windfall.

Deal with the customer satisfaction issue by opening a Paypal account and loading in emergancy money so you can offer an instant refund via a gift certificate if anyone is unhappy... easier imagine then trying to process a charge back and an unlikely evenetuality to say the least.

People will by crap if they have thier reasons I think, the key to a satisfied customer is honest and full disclosure in the promos... I don't belive in a hard sell, either the thing is something people want/need when they see it or it isn't -I won't even read hype promo or ertzat J. Perteman catalog mood-setting copy but I always apreciate merchants who show a default Poser render, a wireframe, and are up front about any failings or limitations of the product in their promo.

I have been greatly impressed by vendors who link to high resolution renders and I almost bought something from insomniaworks soley on account of the promo paragraph titled "Bad things about the product:"!

Anyway, you should not worry about the quality of your work, I put you at the very top of modelers with obm890 and only a few others. There are vendors who actually state upfront: caveat emptor, for IRW reasons I am generally not available for product support, please consider this in your purchase. I belive this is contray to RMP TOS but I have seen it, and I have seen people express gratitude for the forth rightness of it.
