You need to buy at least 200 pieces to get a few bucks off.

Also service comes with a price. If i sell a lens and its not good i send a new one that cost me a lens and shipping cost. Did you calculate that also?

For most hobbyist everything is too expencive. But they expect service also. Service comes with a price. Sure i,m happy to help people with building their projectors like michelrietveld, give stuff that i manufactured and not use anymore for a few bucks away. I build even an 8 combiner for Hobbybob for cheap as chips but he suports me even he sometimes hardly can afford it. Dave helped me with his retainers and so i,m happy to return the favour.
