I also enjoy the hunt for 1/72 options. With 28mm there are so many choices, I would find myself agonizing over what decision to make. With 1/72, anything I come across feels like a little victory.
@crafty - I'm not sure if you're interested but zvezda also has a really great line of Samurai that are plentiful on ebay and a low price. I bought two boxes of each of their samurai sets so i can have two forces at 1/72. Then I picked up some sohei style monk warriors and artillery from Red Box.
The one box I'm really tracking down, and can't find anywhere except a gouger on ebay, are the Zvezda Hundred Year's War English Infantry.
