Honestly, if you are looking for something used, you are limited by what is available. That is going to net you primarily blasts, ninjas, and rebels.
My suggestion would be to go to all of the local dealerships and sit on their bikes to see what you like and then start watching the ads. That way when you see something you are already familiar with you can snap it up.
Also, the word on the street is that the best time to get a good deal on a used bike is around the holidays, into January.
