I have made my own stainless lines and while it looks really nice it is difficult to flare and bend and get to fit right, not impossible, but not all that fun.
If you want stainless the pre made kit might be a good choice.

If you want to make your own lines copper nickel alloy brake lines are very easy to flare and bend, look nice and don't corrode. Copper nickel is used by a number of European car manufacturers and seems to be getting more popular here. I've got some for sale here if interested.
