Not from those sets, but at least here we make steel braided lines in our own garages, as it is easy to find/buy all stuff, like different banjo bolts, that tube, washers, etc... Need to train little first, but its quite simple job. I have made about 10 lines and all function well. Cost will be approximately about 50% from those set prices.
It can also be, that in some countries such is illegal, but it depends about country. I can quess, that in Germany such is never allowed, as everything have to be "TUV labelled" . Here we dont have yet those "year check's" for motorbikes, and polices have much more important to do, so why not here?

Have to be accurate with cutting tube and tightening torques, but anyway easy job.

Edited: I mean cost, not coasts.... my mistake! Or should i say, costs...hehehe....
