I have a whole Samurai army with the foot and mounted Samurai, Ashigaru with bows and yari from the old Wargames Factory line - I think Warlord Games still sells them here:

I really think the minis are great and being plastic they are easily kit-bashed. I will try to post a pic that is on my other computer of my assembled army (alas, not painted yet!) if you would like.
