My latest painting commission (just finished) was for Xyston 15mm Macedonians: 32 phalangites, 12 companion cavalry, and 2 charioteers. I liked the Xyston figures very much, and if I ever build a Macedonian army for myself in this scale, they're certainly what I'll use. At around $.60 apiece, they're still cheaper than ABs, and I think they're nearly as well sculpted.
I painted these in what I think are the most likely colors for Macedonians. You won't see any pastel rainbow here. I went with dull red tunics, off-white linothorax, and straight bronze metal. The shields are, as always, hand painted. If I ever do this for myself, I'll probably spring for some Little Big Men transfers.
