I going by the amount charged for the lot of three which to me wasn't that expensive. I believe DarkStorms (not to say at all that his are too expensive for I couldn't do them myself and I really appreciate his endevours) are somewhat less than that for one lens. I'm using this as the only comparison I know of.
Damn.
