I am just getting into mountain biking and wonder if I could get some opinions from members. I am replacing my old Schwinn and looking to get a newer used bike. On my local CL I found an ad for a Gary Fisher Wahoo. I believe it is at least 6 yrs old but is reported to be in good condition and $200. I was wondering what people think of that as an entry level bike as I ease into the sport. If there is another bike that people think would be better, I am 6'1 and 250+ so I need something pretty sturdy. Thanks for the input.
