Beginner bike for a 14 year old

I'm 14 but 15 next month. 5'9 140. New to dirt bikes. I want to get my first dirt bike for this summer. I've ridden a Raptor 700 so I'm okay at shifting. I want to get either a Crf 230 or Crf 150. I will just be doing trail climbing hills. No motocross. I don't want to spend more than $2400. Any help will be appreciated.
