Okay guys, introduce me to the world of 6mm terrain...

How about the buildings from Monsterpocalypse?

N scale is too big and Monsterpoc too small.
Z scale is better.
Timecast Models, Old Crow (if he ever opens shop again).

Even Z-Scale is around 1/220-1/240...and in typical railroad model fashion, absurdly expensive ($15-20 per building).  I may end up making my own stuff or begging my buddy who has a laser-shop to cut me up some custom stuff...very simple buildings perhaps.
