Dux Homunculorum is a blog run by Alanus, an Australian devotee of 1/72nd scale wargaming (or as he says - "the One True Scale.")
Recently Alanus decided to investigate the options available for English Civil War gaming in this scale. He ended up with several comprehensive posts, including some comparison photos, as well as several pictures of painted and based units. His posts are here:
Part 1, Infantry
Part 2, Cavalry
Part 3, Artillery
Alanus considers the following plastic makers: A Call to Arms, Revell, Zvezda, Mars, Strelets, and GerMan.
On the metal side, he looked at SHQ and Tumbling Dice.
