If I were you I'd get the cheapest 600 I could find, get an older one, so if you drop it it won't hurt your wallet as much. 4,000 to 4,500 US is about what the 2000-2001's are going for. Be careful when buying a used bike, some of them store the milage in the gauge clusters... so many don't display the true milage if the cluster has been swapped. My bike has been looped once and crashed head on into a car the second time. It was repaired both times and now looks brand new again. You would not be able to tell that it's been in two severe accidents; so be careful when buying used. That's why I would buy an older bike for cheap, learn on it, drop it, etc... then when you're ready and have more $$$ I'd buy something really close to new (like a year old) or brand new. That way you know it's truly immaculate and you can baby it.
