OK so I'm about ready to buy my first MTB (been riding road bikes for a long time). I'm not sure if I want to buy a full suspension bike or a hardtail. I found a 2001 Specialized Stumpjumper FSR XC Pro for $800 in the local classifieds and am thinking about picking it up. I could use a little advise as I don't know much about MTB's. My budget is $600-$800.
