Yup... as a customer, I will be prepared to pay more for a niche item, of the right quality. By all means.

Look at the renapd Napoleonic stuff I mentioned earlier. Not the cheapest clothing sets. but they really fill a niche.

Although... there is a heck of a lot in there for your money actually too.  A heck of a lot. They're a bargain at the price they are really, when you think about it!
