Welcome, have you ever ridden a bike before?? If the answer is no then you know what to do I hope. (school, small bike for 1st year, etc....)
A Ninja 250 or 500 would be plenty to teach you the ropes and the nice thing is that you will get the money back when you sell it due to them not losing value. No matter what people say the SV is not a beginner machine. I am sorry to all of you that say you did fine on it. A 70HP bike isn't a beginner bike.
