I notice there are a lot of people, with all the keycap sets on offer, who wish for a specific configuration which is not offered by the maker. Why not solve this issue by simply putting up a questionnaire on each product and find out how many of each layout people are interested in. Sell the keycaps in bags, to save on the cost of presenting the keys nicely laid out in plastic trays. Then you can sell more of them and give people what they want!!?? It makes sense to me!?
