Wayne,
You can always roll your own, only things needed are a varible speed drill a vice to hold the drill, magnetic wire, and epoxy. You can use sewing bobbins for the former to get the wire going. There's plenty of electronic charts out there that will give you the length of wire based on the bobbin size, gauge of wire and how many feet of wire you need to achive the proper inductance. Just keep track of how many revolutions on the drill.Like you have time right. Projects like this I like to call a rainy day waste my time type of project.
