Hey All!  Just joined the site.  Looking for some insight.  I wanted to pass the introduction, and get down to business.  I live in the US, in Colorado.  I am an experienced rider, and been riding 34 of the 37 years I have been alive.  Motocross, Enduro, Trails, etc.  I want to start getting into trials riding.  I am looking for advise on a used bike trials bike for under $2500 or so.  I am 6'3' 280, good shape, but eat too damn much. 
  
Here is my question.  I have found some good late 90's Gas Gas's for $1500 to $2500, but I have heard they are "fragile".  I can ride with finesse, but due to my weight I put a lot of torque on bikes.  Then ad my aggressive nature I put a lot of stress bigger bikes even.  I know that sounds like a contradiction, but that leads me to my question.  What are some of the best built trials bikes from the late 90's and up on a $2500 budget +/-? 
  
Please give me insight on makes, models, and what to look for (condition, flaws, frame stress, etc.) if I find anything to buy? 
  
Thanks! 
Eric 
  
The pic is of me on a XR400R, and they are bikes.  I make it look pretty small.
