So I decided to order IDV a little while ago and they showed up from the UK far quicker than I was expecting, along with another book from Helion's Century of the Soldier line.
I've only skimmed through the rules but combined with the reviews that came out while my copy was en route to me, I like what I see.
I think I'll do some dry runs with cardstock bases just to test things solo, and then look into 2mm Forward March 3d printed stuff for a couple of quick armies with a real mass battle look.
