I would guess "limited" refers to the initial production run (beta test to see what comes out of the sausage machine???)rather than a one shot deal since it cost money to setup a new production line... You have to train the production staff with parts procurement, design, assembly, test, quality control and then create test fixtures, debug stations etc.
Sales Page says "Back By Popular Demand".
Maybe it is now back in stock. Yesterday it was not on the sales page.
Not clear on how limited the production run is.
