If you made a decent spin window that wasn't outrageously priced you might sell a few.

You can spot outrageously or divisively priced products by the complete lack of pricing on web sites, "bespoke products" is often used as an excuse but it simply doesn't wash as a couple of pricing examples can always easily be offered, unless they've never sold anything! :D

I don't even bite and run away from "Email for a quote" suppliers who are obviously fishing to see how much they can relieve you of, and if they are not they should realise that's what it looks like and it puts some people right off ;-)
