Replying to Buy a tramp

im brother and i are putting our money together to by a tramp in the spring, we live in ohio and was wondering were's a good place to get one, i honsetly have no idea at all. 16 - 17 foot is what we are looking for, theres not gymnastics place with a trampoline or a foam pit around us the closest is ohio dreams but thats pretty far, anyway this is pretty much our only option, if theres any other way to learn stuff besides a summer set please mention
