Fireforge Games They recently added fantasy figures to their historical lines so that would give you Pegasus Knights. The Crusader era knights and footmen are close in design to the 5th ed Bretonnians (which is what I had). However, if you want more "modern" knights ...
Perry Miniatures. They have both metal and plastic. You could use the mounted men at arms (knights) 1450-1500 (mid 15th-16th century). While they currently only have Agincourt foot knights, Beasts of War mentions that the Perrys will be producing mounted Agincourt knights in the future.

I was wondering if anyone knew of any good alternatives for bretonnians? I had a some before they quit making them, but I now for some reason want to expand with some more knights, ones that fit with
GW scale nicely would be good. I was also wondering if anyone knew where I could buy a good foot knight ( I guess I could do a conversion as well). I have two
GW foot knights but I am wanting to get some more for literally no reason I guess? Thanks for any help. I guess if need be Ill just buy off of eBay or something for more
GW models.
