I purchased a 12ft Universal Trampoline from Big Air 2 years ago. I have to say it is fantastic. I have teenage children and have had the trampoline put through some rigourous work outs. No problems at all. it has even had approximately 12 teenagers sitting (not jumping)on it at one time and it handled the weight with no problem.
My overall experience with the company has been marvolous, from customer service and the trampoline itself.
I would highly reccomend this company to anyone.

Approximate cost: $319.00
