I make my own jigs but would like to know where I can buy the swivel and Colorado an willow leaf blades to go on the jigheads. Anyone know where these can be bought?

A roadrunner is costing almost $2.50 at Bass Pro. A stump jumper is around $1.50. Is it worth the time and effort to do this and about how much will each jig cost me to make? Do they work equally well is one better than the other?
