Between two used industrial sewing machines priced under $400, the choice seems easy until you notice the conditions. The Juki MS-1190 is sold for parts or not working, while the Union Special 51-400 is sold as used. When you are shopping for textile apparel machinery, the payoff is figuring out which one gets you to garment production and which one is really a repair or parts project.
Quick verdict
Choose the Union Special 51-400 if you need a heavy-duty machine for jeans, trousers, pants, or coats. Choose the AS-IS Juki MS-1190 if you want a Juki head for a repair project or a source of MS-1190 parts. The price difference is $150 with the Union Special on the lower end, but the real difference is condition.

The $150 price spread favors the Union Special. Even with that spread, the Juki is not automatically the worse deal; it depends on whether you are buying a sewing machine for production or buying a parts/project machine.
Where the Juki MS-1190 wins
- The feed-off-the-arm format gives you a Juki MS-1190 head that can be repaired or used for salvaging hard-to-source Juki parts.
- The project scope is clear because it is sold as a machine head without the table and motor.
Where the Union Special 51-400 wins
- It is offered for jeans, trousers, pants, and coats, with 3/16-inch spacing between the needles.
- It is a two-head double-needle layout, which matches the heavy-duty garment seaming work described.
- It is the stronger candidate for production because the condition points to a used machine rather than a repair project.
AS-IS Juki MS-1190
The main reason to buy this Juki is the combination of model name and condition. It is a feed-off-the-arm MS-1190 head sold for parts or not working. It was damaged during shipment and could be repaired or stripped for hard-to-source Juki parts. For someone running a repair bench or maintaining a fleet of Juki machines, that exposure can be more valuable than a working generic head. The clear limitation is that you cannot sew with it as-is. The machine head has no table or motor included, and the unit is currently non-working. Budget time for troubleshooting before production, or treat it purely as a parts donor.
Union Special 51-400
This Union Special is the candidate to choose when you need a heavy-duty machine for real garment seams. It is offered for jeans, trousers, pants, and coats, and the 3/16-inch spacing between needles gives you a concrete guide for seam width. The reason to lean this way is straightforward: the head layout is a two-head double-needle setup, and the heavy-duty spec matches the seaming jobs described. The limitation to keep in mind is that it carries a California Prop 65 warning, which is a state-mandated notice for a shop or resale environment.
Final choice by use case
Pick the Union Special 51-400 when your goal is a heavy-duty industrial machine for jean, trouser, pants, or coat seams and you want a machine to put into shop service. Pick the AS-IS Juki MS-1190 when your goal is a repair project or a source of MS-1190-specific parts, and you are okay with a machine head that has no table or motor.
