Regular steel is good, and will last a long time if you don't drive in salt.

Personally I like stainless lines for my trucks. I feel if I am going to spend the time to make the lines and make them look good I should have a more permanent material. I view steel lines as replaceable as a regular maintenance item when the time comes. I view stainless lines as more or less permanent, a lasting solution.

It is difficult to flare. For a little while you can get by with a good quality, but not a cheap, flare tool. If you make lots of lines then a top quality flare tool is a must, but plan to spend some money...

Another brake line option is http://store.fedhillusa.com/cuniferbrakeandhydline.aspx
A copper nickel alloy DOT approved brake line.
I have used it for two short lines on my truck, and I can see that I will be using it more in the future. Very easy to work with, and just as long lasting as stainless, possibly better all around than stainless.
