Iím in the market for a new touring bike. I have been a heavy commuter for the past two years putting well over a 100 miles on every week. I have never done any real touring, but am planning a coast to coast next summer. I will be moving back to the states in a couple weeks and need to start my traning. The max I have to spend is around $1000. My questions are: Should I just get the best used touring bike for around $500 for training and try and save up for new bike next year? Would a $1000 dollar bike get me 3,500+ miles (but on top of that I would still need to buy all the gadgets needed for touring)? And any other suggestions on the style, brand of bike/tires/panniers for this kind of trip.
