Just to add my point in..
I don't sell my pens....
People buy them.... 
People have brought more commissioned pens from me over the last two years than I have ever done in the last 20..
But everyone has got a point, sell them cheap, to keep a hobby going and keeping you active as the years march on.
Or sell them at a profit, whatever you do is down to you and if you are happy with that then carry on..
Nough said, init..
