The sticky threads at the top of the new rider area are good places to find more info.
You've discovered the major drawback for the new body style Ninja 250 they're very popular, and many people ask more than MSRP for a used bike. You should look at bikes like the Ninja 500 and 650, the Suzuki SV650, Yamaha FZ6 and FZ6R. Basically you need a bike that is more forgiving than the supersport 600's. When you have some experience trade up to a more aggressive bike if that's your style. Don't fall for the "you'll outgrow your bike" faulty logic. Nobody keeps his first bike.
"We didn't trade shoves; I did all the shoving." -Bobby Knight, 1981
