Cigar Box initially had one mat that was a 6" subdued grid, which was branded for the rules Tin Soldiers in Action. After obtaining that mat I wrote Cigar Box multiple times and posted on several forums about getting the grid on other mats. I then heard a 'rumor' that they were adding square grids to two other mats (Desert and Tundra). I checked their website and sure enough, they had added the option. In checking it out, I accidentally clicked on another mat and found it also had the option, so I inventoried their whole line. Here are the grid options for their mats.
All of the mats listed, and the Desert and Tundra mats, have 1", 2", 3" and 4" hex grid options: Space Frontiers, the three River mats, Crossroads, Frozen Ruins, Red Planet, Winter Scrubland, Scrubland, La Haye Sainte, Five Points, Waterloo, Beachhead, Europe 2, Europe Just Fields, Tropical Battles, Winter, Wooded, Europe, Muddy Barren and The Mud and the Blood.
These last two, Muddy Barren and The Mud and the Blood, are surprising for not having a square grid given that they are WWI-themed mats and "Square Bashing" by Peter Pig are popular, at least amongst grid-based gamers.
The following mats have the hex options listed above and an option for a 50mm square grid: Caribbean Waters and Ocean Gaming.
The Ocean Gaming mat has the hex options listed above and an option for either a 50mm or 6" square grid.
The Grasslands mat has the hex options listed above and an option for a 6" square grid as a specially branded TSIA item.
Finally, the Mixed Ground mat has the hex options listed above and options for a 4" or 6" square grid.
From what I can tell, none of the 3' square mats have any grid options nor the specialty battle maps (save Waterloo and La Haye Sainte).
So, lots of hex grid options out there from Cigar Box mats, and an increasing number for a square grid.
