As Inarticulate said, most of the Perry stuff is metal. But as we discussed in another thread, they've got plastic Wars of the Roses figures coming out soon, which gets a big
from me.
I think you may already be familiar with most of these, but just for the sake of mentioning it and collecting references...
I think you've seen elsewhere that I'm a big fan of the Front Rank Wars of the Roses range, as well. I use them for both Empire & DoW figures. As much as I'm a fan of the puff & slash landsknecht style, I've also become increasingly fond of doing a "historical Empire" army from the past, before the puff & slash. Sort of like they were portrayed in earlier editions of the game. Along those lines, some of the Crusader Miniatures WotR range are good. The cavalry fit better with WFB and Front Rank figures, though -- the infantry are well sculpted but thinner and more "realistic" looking.
Foundry is good, if somewhat expensive if you live outside of the UK. But in addition to their landsknecht range, they also have conquistadors & Elizabethans. Not only that, but they have a small number of orcs & dwarfs in costume of that period as well. Maybe something to use as DoW (dwarfs, Rudluds, etc) in an Estalian themed army.
Then, of course, there's the Black Scorpion's human, orc, gobbo and dwarf pirates.
Black Hat has more orcs, dwarfs, gobbos, etc. in a sort of Elizabethan/pirate theme.
Vendel Miniatures' fantasy figures are more dark ages themed, but they have a small range of Elizabethans (including their Irish & Border Rievers ranges.) A lot of the English are wearing morions and could probably pass for Estalians. I'm very curious to see these figures in person. They look great (and tempting!) on the web page.
There's also Old Glory, for a variety of historical figures. Plus I think at one point they carried various "dwarf wars" figures (Or were they by Blue Moon?) that were themed to different historical armies.
If you want ECW, in addition to the plastics from Warlord, mentioned by Inarticulate, there are also some great sales/deals at Renegade. Their figures are bit bulkier and closer to GW scale (if not bigger!).
