Here are some Arab heavy cavalry from the Gripping Beast plastic set that I've just finished painting for my Islamic armies. I have a box of the plastic GB light cavalry to paint as well but have more Perry horse archers and infantry to finish before them. I find an initial aim of a 24 point Lion Rampant force works well as motivation for completing units for a game and is very achievable as you usually only need five or so units a side. I will use these as Seljuks and Syrians against my Crusaders and Byzantines.
