If you like cruisers it's hard to go wrong with a Honda Shadow 750 or a Kawasaki Vulcan 750. There are loads of used ones. Get a year or two experience on one then sell it for close to what you paid for it. They are mildly tuned bikes that are easy to ride and have enough power to run on the Interstates. Since you are learning you want to stay away from the 700 pound bikes.
You might consider learning on a Dual Purpose bike like Kaw's 250 or the Suzuki DRZ400. They are about the easiest bikes to ride and pick up when you fall over. Dirt experience is invaluable as well. You learn to do the basics while not having to avoid Joe 6pack in his cage.
