Hello Gav, here in Texas I usually round off the kit price to the next 5 dollars and add !0 dollars (about the U.S. minimum hour's pay
) to the price, so I sell a slimline for 15 dollars (or 10.00 Pounds). I know that is a little low, but as Mattyts said above, "It's a hobby not a business." I would add however, like most things, they are worth what you can get for them.
