Alright well now I need some that are cheaper because I aint paying that much for them.
If I had to guess, this ^ mentality is a large part of the reason we don't see more people manufacturing drivers.
Do the math. For a seller to list them at $20, they probably need to buy them from whomever is making them for under $15. Whomever sells them for $15, probably has to buy parts for $5 to $10, and then has a time investment in reflowing them. There's almost no margin here, and that's pretending there are no upfront $ or time investment in designing the driver itself. Plus, as demonstrated above, people are already complaining about the $20 price tag.
You should be happy that someone will make drivers, and someone else will then sell the drivers, all for an end price of around $20. I say "you", not to point a finger at you specifically - I mean the forum as a whole. I'm blown away that both Lazeerer and Flaminpyro are willing to continue doing this. In my opinion, it's a gift to the forum, moreso than anything else. I cannot imagine that either of them are making money (or any signficant amount) selling buck drivers.
That said, if you don't like paying $20+ for a buck driver (and I'm in that boat with you - I don't usually buy drivers) then your option is to create your own. Consider it an extension of the hobby. Build your own buck driver. There's a learning curve with switching drivers, but it's not an impossible task (as many used to claim). As long as you don't mind spending a couple hundred dollars on parts, iterating a design, investing the time, and reading a LOT, there's no reason you can't pull it off (even coming from a starting point of having zero familiarity with the basics of switching regulators. Oshpark, Digikey, and datasheets are your friend
