Recently joined and found this forum after looking to get back in to tabletop games such as GD and AoF...quick google search for papercraft minis following the amazing work that labratblue has done, I found some of the following...reasonable prices, just need bases, which they also have plans for.
Another easy mode free option: Chibi hammer 14k minis, how I got started with papercraft
I've been a paper model designer for nearly 20 years (as Michael The Haggard) and sold some things on DriveThroughRPG. I have been a 40K gamer for about 15. JUST found ChibiHammer a few weeks ago and love it. I live in a small town now with people who want to play but who cannot afford the 40K minis or books. Chibihammer and One Page Rules are THE WAY to go.
A nice option for those who aren't much into the hobby aspect (crafting, painting), they're quite unexpensive and it seems they look decent on the tabletop (haven't got any myself, so I judge by just looking at pics on website). Selection isn't very wide atm, but if they'll get some success it's probable the line will grow.
