I am also waiting for a trampoline that was supposed to be a Christmas present for my daughter (I was happily planning on sharing!). It was supposed to be delivered by late February. Fortunately I haven't paid for it yet, so I'm not out any money. I really have my heart set on a good rectangular tramp and I have begun looking again for a great deal. I would also like to eventually get a Trikke. They look like fun, and look like a good workout to boot.
Feel free to comment on anything that has helped you go from a heavy runner to slim runner, or just from a heavy person to a less-heavy person.
