Doug:
I think you would be cheating yourself to get a MFT Basic as your first MFT.
On the MFT/3, the accessories can be removed and replaced without changing accuracy. You position the guide rail elevator/mounts against a stop on each side of the table, which remains in place and out of your way when they are removed.

As long as you don't bang around the pivot mount significantly when it is disassembled, it will return to the same place. The pivot mount is the one with the adjustment. It takes quite a rap to knock it out of alignment.
The same is true of the fence mount.
The fence mount is located on the table profiles (extruded aluminum frame) by the v-groove on top so they return to the same position relative to the table when removed, replace, or moved.
