I don't know about your machine upgrades. Does it use the USB or card reader for EMB?

It seems there are some new machines due in August. You might check those first and then decide if the upgrade fits your needs. They are putting more features into the machine software to enhance the capabilities right at the machine vs a stand alone software. Some of the new machine have wireless transfer of designs also.
I did the upgrade to the Spirit and quite happy with it. It was an easy process to load and added the 8x8 hoop size. I also did the upgrade for the dream and the software. Again easy processes.
Good luck!
