Replying to WTB: Used Mountain Bike, Full Suspension or Hardtail

Seeing as my Trek 6500 was stolen and I do not think I will ever see it again, its time to start looking.  I will be going to UVM in the fall so I am looking at used bikes instead of new incase this one gets stolen.  I was looking at a Marin Bobcat for hardtail and any low end full suspension.  A couple years old would be fine.  Not looking to spend too much, probably under $500.  Hit me up with anything.
