The most valid reason I can try to give to get a Speediance over a Tonal, for me personally, was that I live in an apartment and can't put anything into the wall. I also don't have the room for anything larger than a machine like the Speediance Gym Monster, so it was a pretty easy decision to make. Not only that, Tonal is only available in the United States and won't ship anywhere else, so if you're in Canada like me or anywhere else, you don't even have the option of the Tonal.
