Replying to In Ground Rectangle Trampoline Coast?

How much is it to get a rectangle trampoline (like a really bouncy one) and then for it to be installed so its level with the ground? I'm really interested in buying one or just a in ground trampoline that will be REALLY bouncy. I don't want to spend a ton of money though I do understand these are expensive. So I need some help finding one (whether it be used or new doesn't matter) and then how much it will be to get it to my house and have in installed so its in ground. Thanks NS!
