Yes, I have grown to love 1/72 when I first built my DS9 Runabout. I used 1/72 aircraft figs on the diorama. I remeber a ton of them came in the box and I enjoyed detaining them to look like starflet engineers. It's hard for me to find that scale of fig now.
I also build Gundams and have recently gotten into Zoids. You can find Zoids dirt cheap now at Kay Bee [and Toy Liquidators] and on clearance at Walmart and some K-marts. I recommend trying Kay Bee/Toy Liqudators. I'm going to find more 1/72 scale figs for Zoid dioramas.
