I don't think that anyone thinks you overcharge. It's simply that some people don't feel that what they cost is worth what they provide. Not that the materials and effort you put into them don't cost as much as you're asking.

However, to be perfectly honest, the way you constantly deride said people doesn't exactly inspire them to change their minds, and it probably does change the minds of some of those who simply hadn't yet gotten around to purchasing them, myself included.

At the same time, I'm sure all of us appreciate, in general, the effort you put into making these and providing them.
