i went to a store that makes trampolines in my city and got a rectangle one, it is basically between a normal trampoline and a gymnast trampoline, the cool thing about it is it is built really well so its basically as good as new after 3 years, and if anytrhing ever got bad, there is a lifetime warranty on everything, and the springs are soft and have a pretty slow rebound, so it isnt as jerky on your back, but still sends you up alot higher, and is way easier to do tricks on. i really reccommend putting down the extra money for a good one, but hey a trampoline is a trampoline and you'll still have tons of fun, andbe able to learn tricks on a normal cheap circular trampoline
