If you're a rookie (like me), you should consider doing everything in with carbon steel tubing first for practice. You can get CS tubing very cheap at your local auto parts store.
You don't need a hydraulic flaring tool. Just get the Eastwood one from Amazon - you have to put some extra elbow grease on SS flares (make sure you double flare everything!) versus carbon steel since the material is a lot less malleable. They have videos for this tool online.

I ran all the brake lines for my 69 firebird (you can see some photos in my build thread) and it worked out great. I can't stress enough to form everything in CS first. Also, on the bender - just get a cheap-medium priced one from amazon or your local parts store - try to learn what the marks on the side of the bender mean. Use the throwaway CS to experiment. This will save you time in the long run.
As far as pricing goes, I think the best pricing you will find will be Jegs or Summit. Buy it in rolled spools, not sticks - it's cheaper that way.
