Im considering buying a fairly serious mountain bike to put to some good use starting in the spring. I will be riding almost everyday on my campus which is rather large (U. Maryland) but on weekends I anticipate heading to N. Virginia. I am looking at the Trek Fuel 80 or Possibly a Fisher Sugar 3 or Fuel 90. Will I really notice a difference in spending the extra money to get the better bikes considering I have no intentions of racing or competing, just somewhat serious recreation. Feel free to make any other suggestions too, and suggestions on best places to buy are always welcome! Thanks!
