I got one, I love it. I beat the shit out of it from time to time, but it never complains. Just because it is a 600 and not a supersport, don't doubt for a second that you can get in over your head on it. The beast bears its teeth around 10K, and though it is no rottweiler, it's not a terrier, either.
Would not my first choice if I had more money to spend at the time, after all it is heavier than SV650, and not as good looking. It is a bitch to pick up when you drop it. The seat really sucks for rides longer than 1 hour.
Other than that, I have learned to feel with the bike, and for the past couple of years I put a lot of miles on it while commuting to work.
