For those that don't want to spend any money, though, there's always the option to create your own. Most of the tokens are on 1" discs, so 25mm bases would work as a substitute. The objective tokens are on 1.25" hexagons, so 32mm bases work for them. And the shaken tokens and wound markers (the latter from the Commanders expansion) are on .5" squares. I've seen a number of interesting innovations such as putting each of the main tokens (Move, Advance, Charge, Fall Back, Ready, and Shoot) on a 1" cube face (much easier to pick up than the discs). Objective markers invite lots of modeling creativity.
I'm developing files for downloadable/printable tokens that players can get for free. While the plan is to have a variety of options available to cover various factions, I've started with tokens themed for the Bolter & Chainsword site's mascot Chapter, the Legio B&C.
Yes, they are the correct sizes on the file. These are just 100 x 100 pixel images.

As an ongoing project, I have the basic template created, so creating tokens for other factions will mostly be a matter of getting the right background and icon. You can see that I've used the Legio skull for the Legio tokens, with a red text background. Imagine Imperial Fists tokens on some sort of yellow background, with the black fist replacing the skull (and the other tokens would probably have black images with a red border vice the white images with a black border that you see in the Legio tokens.
I'll take requests, but progress will be slow. Requests for factions for which the requester has an actual painted kill team will have priority.
I'd also like to see other players show their own homemade tokens for Kill Team, or even tokens purchased from third parties.
