Brake Flaring Tool....Best to Buy???

Here we go again with more tools in my shop. What brake flaring tool is best for the non-professional? I purchased the Amazon "red box" special with 25 ' of tubing and the tool is junk or I don't know how to use it. No instructions and I am relying on IN Line Tube videos for help.

Who make TLF products? They have a nice assortment. Pls tell me what I should buy for replacing old and rusty brake lines w/ 45 deg flares? Tube diameter is 3/16 in.

Thx...love MOPARs. Stay safe and healthy.
