Express Action Sports

I’m possibly attending Camp Woodward this summer and I’m trying to figure out which camera I should buy for their Video Production camp. We film for Action Sports (specifically skateboarding and BMX), so if anyone who is perhaps a former Woodward camper or skateboard edit filmer, please help me!!!!!
I want a camera that’s going to last me for a long time, and something with HD, and hopefully not used. I have a price limit of about $3,000, but I can make my budget fit around it.
Thanks.
Also, I’m not looking for a GoPro right now, but if you’d give me any advice about that, it’d help.

GoPro would be the way to go.
