Wargames Foundry (and the Casting Room spin off) have extensive ranges of Medieval Knights both mounted and dismounted.
My concern with the really old ranges like this and Essex is that they will look too out of place on my table. Shame, because they really do have everything. Love those Warmonger Miniatures orcs, tho
Steel Fist miniatures do some great knights.
Wow! They really do! Those helmet plumes are fantastic!
2 years ago, I would totally have pushed you towards the Thunderbolt Mountain range. Maybe eBay?
I know!! I bought some stuff from them right before they shut down, I remember seeing the whole gang of Arthurian knights mounted and on foot!
Thank you all for the nice suggestions. Scavenging some perry or gw stuff off ebay seems like the best bet, so I'll start there. Great idea to look for single sprues, I hadn't thought of that. Those steel fist italian knights are quite tempting as well...
