I chose prepainted fig's, but then I realized I do use tokens and I have a heckuva lot of 1:72 unpainted military figs. I have 3 complete sets of Star Wars Minis (amounting to about 500 figs total), about 100 Heroclix, about 50 MechWarrior figs and about 300 unpainted military figs. I really wish I'd gotten into some prepainted Fantasy figs, but I didn't and there isn't much of anything at any of the LGS's in my city. I use tokens for some military aircraft and navy vehicles. Whenever I need a 1:72 or 1:60 scale modern vehicle, I usually just find a graphic and then photoshop it to scale and turn it into a laminated tile or token.
One of the players in my gaming group is a real 1:72 model enthusiast, so at any time I have about 20 armored cars, APC, tanks, jets and WWII props on hand - some very authentically painted, some not painted at all. He also supplies me with a lot of nice 1:72 military scenery.
I'd love to have the time and resources to paint figs like I used to in my AD&D days, but the reality is I just don't.
