Just buy a quality double flare tool and tube cutter. Then you can make anything for cheap out of parts store lines etc. I bend line with my hands, some people like to use bending tools. You just have to be careful to make a radius so it doesn't kink.

I only buy prebent/flared if I'm using stainless. Some say stainless is too hard and doesn't seal well but I'm a fan of the durability.
