You can buy lifts separately.
Here's one:

If you get a standard sized hole cut for the machine, you can get inserts. Koala should make one for your machine if you cut the hole for the lift the same size as a Koala or Horn. 18-13/16" X 11-3/16"
I have a Koala Lite, and a Horn, and the the Pfaff 2170 insert fits both perfectly.
