I know what you mean...having been there, done that and in some cases, still doing it. For whatever reason, I still peruse the MRL/Windlass catalog and if I see something I like, I might get it- even though it'll be anachronistic and not authentic to any one period, if at all. That applies mostly to swords though, and the occasional garment- never the armor as most of it sucks both in quality and fitment.
Funny you should mention windlass, recently I have been eyeing up their
European Sword for I have heard it was a fairly decent blade and in my budget. But according to the Windlass site it is a 15th not 14th c. Sword. The only armor I wanted from there was a bascinet ment to be worn under a great helm. Therion arms was selling the product too. Sadly both discontinued them.
