Me too Phil. :bravo:
As turners and woodworkers are we not by default trying to make unique and different items anyway or should all slimlines be exactly the same shape and colour, might as well just buy a box of Bics 
I repeat, you don't need bushes to make a pen and if you decide the opposite then its a simple matter to make some. The original post was suggesting that bushes are a rip off and again I repeat, if someone buys a set of bushes off your site for example at under £4 and gets 20 pens out of them that's only 20p on the cost of each pen and in practice you'd get many more than that so hardly a rip off, I doubt you'd lose much sleep if you didn't sell them. They aren't going to buy you that Ferrari are they.
