Replying to Trampoline Recomendations

I posted this in the trampoline cult but that seems to be dead. Ive been searching for a new trampoline for quite some time now and to be honest Ive made very little progress. I don't want to drop 500 + dollars on a tramp that's big but doesn't bounce well. Does any one have any suggestions on tramps? I found these two tramps but couldn't tell how they bounce by the description.

Thanks A lot! I know I and many others have had problems finding a new tramp.
