Museum Repilicas Ltd. is a good start. (

For more ornate, slightly more expensive, and better-made weapons, try Arms and Armor. (
www.armor.com )
These are both excellent companies: well-made weapons without paying several thousand dollars to a custom smith. MRL is frequented by the Asoociation for Rennesance Martial Arts; these guys do a lot of live-steel ( rebated edges ) sparring and test-cutting, so their weapons have to be able to take quite a bit of abuse. Both companies also base their entire collections around existing examples or archetypes developed by Ewart Oakshott.
