Definitely keep an eye out for private sales! Depending on how much money you have to spend I believe all 03 + and up models have fuel injection and are generally equal in build! I just found a handful of nice ones on CL for good prices. Obviously some might be fake, or garbage, but give them a run through a moto mechanic, they'll be able to check important functions quickly!
