Reddit mentions of OneBallJay Nylon Brush One Color, One Size

If you source the pieces yourself you can get what you need. You usually don't need everything that comes in a kit. Buy the additional pieces as you need them.

Here's what I found without much effort:

$35 iron

$23 wax (huge brick)

$6 scraper

$14 nylon brush

$6 scotch brite sponges

That's $84 and is all you need to get started. You can certainly get kits for around the same price that include some edge tuning bits, but they also come with a very small amount of wax and surprisingly often they don't include any brushes, or just a wire brush.
