If you're just fixing to play with friends and not in tournaments or local gaming shops there is the option of printed card tokens, which are generally a big no-no when it comes to official play, but nobody's gonna police the little games you play with friends.
It's a different system, but One Page rules has a starter set with paper minis you can print out. If you find that you like it you can buy actually Warhammer models and try that rule set.
I've also played Warhammer online via tabletop simulator.
