I have one for sale. You need at least a 12 foot tramp, the 10 foot ones are too small. I live in Roseville Ca. If you are local, I'll sell it to you. I don't have a box to ship it in, so I'm looking for someone within driving distance.
I've got a 16' Round (brand) Trampoline. They're quite a bit more than most others, but if you're willing to throw down the cash you won't regret it. They've got galvanized springs and frame (instead of the steel/aluminum most use), and double mats on the larger sizes. This makes them much more firm than most others, which can take some getting used to.
No. They had the safety net there, but I didn't know it until I was checking-out with the security guard and he told me. At that point I didn't feel like going back to get it.
