any advice on which steering damper to put on and any idea of the price
The Scotts raises the bar around 10mm. I hardly noticed it.Some dampers modify your control position quite a bit (Scott), mildly (GPR) or not at all (Ohlins kit by Dan Kyle, Ducati Perf, Matris). Something to think about. I for one did not like the higher control position that came with the Scott clamp kit an wouldn't put one on even if I found it in my driveway. A taller rider might have a very different opinion. Also the level of finish is very different from one brand to another. There is no 'best' damper but if you spend some time comparing them you'll find the one that works best for you which is all that really matters. YMMV.
