I've got a fair few units of archers in my Roman force. You get one unit in the Pendraken 1000pt starter army, and I then picked up another 100 or so Pendraken figures from a friend who wasn't using them, which gave me a second unit. Finally I picked up a couple of packs of Pendraken greek archers at Colours one year. I thought with the addition of some Pendraken Roman command figures they would make great auxiliaries.
The figures for both types from Pendraken are solid without being spectacular. Obviously only have one pose does make for a slightly boring job painting them, but on the flip side you can race through them batch painting. The tunics and hat brims on the greeks are nice, as there is enough recess that a base-wash-spot highlight really make them "pop".
