If you're like most card model builders you're going to find that in a short period of time you will have acquired more free kits on the web than you'll possibly be able to assemble in one lifetime! (We're working on extending lifespan for just this very reason!)
Here's some links to help shorten the "finding process", leaving you more time to assemble! These are English language pages.

Let me know when you have all those assembled and happy building!
