I have Tektro CR720 and Shimano CX-50 canti brakes on four bikes, including touring, sport touring and cross bikes. Both brakes function great and cost much less than $100 a set, but work much better if you replace the stock pads with KoolStop salmons. The Tektros can be bought for about $35/set but they do jut out a lot on the sides if that is an issue. The Shimanos are little more expensive but don't jut out as much.
