Dealers, Smiths, Armorers, Seamstresses -

Blacksword Armoury, Inc

In Florida, despite the name. Hard to read, poor spelling at website details turn me off.. but looks like quite an inventory of imported items. Imports always make me wonder if I could find it cheaper somewhere else..

Bugei Trading Company

"Real" traditional Japanese Samurai swords. Nice looking stuff, pricey. Looks worth it, if you want a real sword.

Chivalry Sports/The Renaissance Store

With a retail store in Arizona. Nice inventory of SCA approved plate armor pieces at reasonable prices, stock leather armor (I might need those vambraces for just $33!) - weapons, clothes, sewing patterns.. I didn't check it all out! The clothing inventory is nice, you could whip out the credit card and get costumed here quickly, it seems.

Valentine Armouries

They're in Alberta, so they can spell it that way... And man, do the do a thorough job on some nice looking pieces, just the tour of their inventory is a nice overview of the history of armor.

Museum Replicas, Limited

More selections... fair deal of nice looking weapons, moderately (?) priced. Thanks to Matt for the pointer to this one.. keep tipping me to 'em, people. ;)
