i was jk about pista concept...bike island has a brake setup (lever, cable, cable housing, caliper) for like 30 bucks or something. Go check that site. You can install it yourself no problem as long as you have some wire cutters. Very very easy. Also, go to your LBS and if you're nice enoguh, they will probably give you a brake for free/cheap. Bike shops usually have tons of extra parts lying around, especially brake calipers, so you can probably get some there. A little cross lever you will probably have to buy, though.
