If you have access to a 3D printer this might be an inexpensive alternative:

Personally, I'd go with the version that has a slight taper.  In most cases it would make no difference at all, and it's quite a bit simpler.

OpenSCAD is free and extremely easy to use, and the parametric design allows you to make a coil exactly how you want it.  If anyone needs it, I can make a video that walks you through the entire process.
