I found this website online that sells paper models. I am posting it here, for all interested. They have a wide variety of all kinds of subjects. They even have 2 models under "Miscellanious" that are free to everyone (Registered member or not).
I don't know if it is a short-term thing or will be there forever, but they also have an offer running, where you can get 3 free models when you register (No clue if they choose, or if you choose) Plenty of subjects from across the realm, all very cheep, and exelent builds between kits, or when you need a break from tedious tasks. All you need is a printer, cardstock, white glue, and a sharp #11 blade (in the hobby knife).
Another perk is, once you download the original file, you don't need to purchace it again, just print them out as many times as you want (Definately going to do this with the free models) and build them.
Here's the link:
