I didn't find an answer, so I took some time this morning and compared what is now offered in the TF Basic Kit to what is sitting in front of me. They didn't make it easy.
I have the Turbo Fire basic kit, bought at the beginning of last summer. From what I can tell the new basic kit:
* Does not have the (high impact) HIIT 25
* Has a Fire 40 that I don't seem to have (could this be a renamed Fire 45 EZ?)
* Renamed Fire 55 EZ class to Fire 55
* Does not have Fire 45 EZ
Can someone else compare, too?
And FWIW, I did get the Greatest HIITS dvd "free" with my order, and it has a $19.95 value on it. I think someone said it now has a $29.95 value on it.
