My sense is that many reloaders have some simple system such as portrayed in this video. For myself, I anneal a low volume of casings (less than 50 at a time) and can't justify spending a large sum. I actually have a Hornday Annealing Kit that is not made any longer plus a cheap electric screw driver that turns a casing (placed in one of the Hornady Kits inserts) at a low RPM, using a single torch and it's worked for me for years.
So if you are thinking about inventing something new, go for it! But you won't really know how well it will sell until you come up with the protype and actually market it. That's when it'll prove to be a seller or not. I suspect that even as nice as Hornady's idea was with their simple annealing kit, they didn't sell enough of them to make it work their while since a simple socket works just as easily using some other simple tool to turn the casing.

I use the Hornady kit - I spoke to them a few weeks ago about the kits, and they said they discontinued them because of low sales volume. Well, that makes sense, since you could buy a set of sockets, a propane torch, and a bottle of propane from Home Depot, for what the Hornady kit costs.
The kit was about $50-ish, and a set of sockets can be had for $10 at the local Pep boys... and you use the sockets to work on your car, when you aren't annealing


The problem with low cost machines is that they compete with the socket and drill method, which can produce 200 perfectly annealed cases an hour - and most people won't anneal more than that at one sitting, so the market for machines is very limited. The socket and drill is $10 to $20 IF you don't have the sockets and propane torch

To get $150, you need to add a fair amount of convenience/mechanization/semi-automation to make it worth while.
There have been several low cost, automatic machines that were well designed, but failed in the market after a short time.
