I'don't start at pig iron miniatures, then look at West wind. However as others say size can vary quite a bit.
Murrmmerrrmuttterblloominnewtabletmuttermurmer - right, predictive text off!!! Why does any program on any device I ever use never predict the words I actually want to use and despite me telling it not to does anyway?!!
"I'd start" not "I'don't start".
Pig Iron, West Wind, Crooked Dice, Maxmini . . . .just hunt around. Finding the best match is tough because they all vary a bit. What sort of heads are you looking for and with what miniatures are you going to use them with?
