With the “riding season” coming to an end for a lot of people, many bikes are being off-loaded to the used bike parket. Nothing wrong with that. Figure out what you want, then keep your eyes out for it in craigslist, local ads, postings on various ‘net BB’s, etc.
When I was looking, I’d narrowed it down to three I’d be pretty much equally happy with — the SV650, the Ninja 650, and the FZ6 (it was worth the price difference to me to not have to deal with a choke). The bike I found was on craigslist, and I answered the ad within 5 minutes of it being posted. I bought the bike the next day, after meeting the owner at a mutually agreed-on location (he rode the bike there, so I knew it ran well).
In any case, don’t feel that you have to buy new. You can find one that’s already gone through the “break-in” period, and has been maintained well, and save you a bundle of money.
