Definitely look around for something that has been lightly used. I picked up my Stumpjuper FSR Elite 29er last October. I searched around on craigslist for a while before finding what I was looking for in my size, Fox Fork, Fox brain rear shock, XTR rear, dropper post. I had to drive a couple of hours to get it, but it was definitely worth it. I was able to get a bike that was about 6 months old with what I would guess was less than 100 miles on it. The thing still looked brand new. The retail price on it was $4200 + tax. The guy gave me the original receipt that showed he paid $4300 out the door. I picked it up for $2500 cash. It still makes me smile every time I ride it.
Now I am looking for a full suspension ladies bike for my wife. It think this one is going to take a little longer to find.
