I'm not sure what the rate of exchange between the US dollar and British pound is, but I sell a simple slimline in basic plating and "found" wood for $15. I add $5 if it has a stylus on the clip. If it is an exotic wood blank I had to buy, I add $5. If it has semiprecious stone inlay, or decal, another $5. So, for example, a slimline in pecan (found wood) would be $15. If it has a stylus, $20. If it also has turquoise inlay or a decal $25. Simple slimline with a purchased box elder burl blank, $20, etc.
