Along the lines of what Mirrortints is saying, you never mentioned why you are buying ss lines. I know that you didn't ask for advice on whether to do this, but just where to buy, so please ignore my input if it's not welcome.
BUT, you seem to be looking to spend as little as possible and the least costly thing to do is to keep your OEM lines (or buy standard replacements if you need replacements). I drive 2 Classics -- one every day, the other on the track. The dd has stock brakes and lines, the track car has ss lines with NX2000 front brakes. When I switched to the ss lines, there was no dramatic change in pedal feel. So if you are looking for a dramatic change in braking or pedal firmness, you will probably be disappointed. On the other hand, the dd car, with stock lines, calipers, a properly adjusted brake pedal, and good pads has an equally firm pedal and is more than adequate for street driving in my opinion.
One thing I do not like about the ss lines is that they are less flexible than OEM and, therefore make it harder to swing the caliper up to change pads. Also, they may not fit the clips that secure them to the strut housing, so you may have to jury rig something. What you will surely get from the ss lines is bling, better heat resistance, and maybe improved resistance to damage from flying debris. If this is what you want, then go for it.
Just my 2 cents worth.
