Overall, I was pleased with Cathy's service. She kept in touch and responded pretty quickly to my emails. She sent plenty of pictures and fixed a few details on the lancers when I pointed them out (example: she had painted the sabre scabbards white instead of bright steel - difficult to tell from the pictures I sent, and white matched the belts and such). For $2 per 15mm cavalry, I think it was a good deal.
So, if you are thinking about sending some of your massive lead pile out to be whittled down, I would say give Cathy at White Ape a try. I will be sending her some more business in the future, after all my Historicon spending is done and I get back to a 'normal' gaming budget.
[Post Script Added 06.10.09: Cathy has offered to refund my money on the three cavalry figures I am not satisfied with. Sounds more than fair to me. I like doing business with folks like this, who stand behind their work.]
