Having just purchased a band of plastic figures, it gave me the incentive to not only paint the new additions, but also some of the figures in my spares box.
The plastic additions came from a trader that supplies odd/single figures. Its not a cheap way to purchase, but he only charges a single postage, regardless of how many you purchase from him. I have been waiting a long time to acquire the mounted saracen, I even had the correct horse and saddle-cloth in my spares box. The other figures helped moderate the postage charge. There was one loss, the bareheaded figure just did not look right, too large, I got rid of it.
