Jules, I hope you have had some control over what your Chinese factory actually produce. In the past, in the HO model train industry, such and such company announces a new locomotive that will only be produced in limited numbers only to find out later that the factory was selling them out the back door and as you say flooding the market.
I like your products and your service but I still hesitate to pre-order anything from anybody. After seeing this one online I decided to jump on it ASAP and get one from England. I have a feeling that the US vendors will sell most of what they can get pretty fast.
One additional comment. Some of the images looked as if the yellow lettering was thin and had bleed through of the blue beneath. But after seeing the model in person it is obvious that the yellow is a darker shade than I originally expected but there is definitely no bleed through and after looking at all of the images that are readily available I think you hit it right. Great job on a terrific looking slot car.
