I just bought everything yesterday. I put the nap quicktune 2000 on my Razortec and I am VERY PLEASED so far. I' ll be paper tuning it today and the pro shop will take care of all the adjustements for me making it very easy. It' s been extreemly quiet and accurate to this point and has worked flawlessly. It also cost less than half of what they wanted for the Muzzy which is a lot of $$$.
