Magister Militum have been rounding out their 3mm historical miniatures line, and we now have stock here in the U.S… We have the complete range, including figures for Ancients and the Age of Reason.
Typical infantry packs contain approximately 480 figures for $21 USD, and cavalry packs typically contain 120 figures for $14 USD.
Infantry typically come in strips of eight figures, cavalry in pairs.
Naturally, at this scale figures can be used for a fairly wide variety of periods. Cavalry in lobster-pot helmet, for example, work for both the Renaissance as well as the Age of Reason.
