The rotary styled stabilizers like the Precision are well worth the extra cash if you can dish it out (about 485 I believe retail). The performance from these stabilizers is second to none.
I run a denton stabilizer right now and it's a great impovement over stock, most bumpsteer is eliminated and I get cooked pretty fast on a bike without one. Just checked the Denton site and noticed it's been updated recently...they have the rebuildable dampers for 160$, as where the non-rebuilds are 140$. If you go with this style dampner instead of the rotary style like the Precision or Elka (which are a step above the style that Janssen/Denton/etc sell), be sure to order a rebuildable. Extra 20$ and you don't have to throw it away when it goes out
