I'm looking for a light weight, low power scope for a .45-70. I see that Midway sells a Leupold variable 1-4x20mm for $229 and a fixed 2.5x-20mm for $269. I've noticed this kind of thing for other manufacturers as well.

Why do fixed scopes often cost more than comparable variable power scopes? It seems like something with a moving part should cost more.
