The good thing is that bikes come up for sale all of the time. If you are questioning the 950 I would suggest you grab a 5 mil allen and take it with you when you go to look. It would be worth the peace of mind taking the few min it may take to remove the plastic cover and have an unobstructed look. You can see behind the cover but if you really want to have a look take the 5 bolts out. You may need either a T handle or possibly a crescent wrench for leverage to break them loose. Good Luck with whatever route you take. Plus I know its a big investment and nobody wants to get taken but keep the info on the internet in perspective....not every 950 has or will have the problem. Good Luck! Rootin for ya because I have the 950 and I really like it. Although between you and me....I wish it had a 6th gear...but thats just me.
