Mountain Bike Dual Slalom

What are some of the best and cheapest dual slalom mountain bikes.?
Im 14 years old, 5 feet 4 inches and 110 pounds and i am looking for a dual slalom mountain bike. I want it to be a good durable bike that is under $1500. What would be a good size bike for me. I you know any thing else that would help me i would appreciate it.
Thanks, Cole
I would look at hardtail dirt jumpers such as the KHS dj’s, Kona stuff, GT chucker, Jamis komodo, and Specialized P bikes.
