On the used market, you will have the benefit of not being locked into the Suzuki feature pack. I got mine very cheaply, new, otherwise I would have farkled a base model. Keep an eye on the for sale section. There is a regular parade of wonderful bikes there and I bet you will be able to find one that exactly suits you.
