LA Choppers kits are nice, havent heard anything bad. Have heard negative things about the Burly kit (search it), ^ Magnum like mentioned above is pretty well the leader in aftermarket cables I think. Only needed to do the brake line on mine, went with a Goodrige set-up, very nice quality.
I just ordered the +8" black Goodridge Ebony brake line kit and the +6 Motion Pro black clutch cable..$189.00 fre freight. I didn't need the throttle and wires extension to do my 12" apes.
I used the Burley kit; had problems with rough pull on the clutch cable. Lubed it several times, it helped but never really cleared up the problem. All the other cables and lines were fine, just the clutch cable was a problem
