Two used industrial sewing heads are sitting in front of you, but they are not interchangeable. One is a blindstitch head for finishing hems; the other is a double-needle chain stitcher for heavy seams. The fixed decision is which stitch type belongs in your shop.
Quick verdict
If your daily work is blindstitch hems on skirts and pants bottoms, the Consew 1099 CS-1H Blindstitch Head Only Industrial Sewing Machine is the purpose-built choice. If your daily work is heavy double-needle chain stitching on jeans, trousers, and coats, the Industrial Sewing Machine Union Special 51-400 double needle chain is the better match. The two used, mechanically operated heads are listed $49 apart, with the Union Special at the lower end of that range.

Product notes
#### Consew 1099 CS-1H Blindstitch Head Only Industrial Sewing Machine
This head earns its place in a shop that finishes garment openings. The one-needle chain stitch blindstitch design is aimed at skirts and pants bottoms, so the stitch role is clear from the listing. It is a Consew industrial head built in Japan, and the seller includes a knee lifter lever. The catch is the phrase head only: the listing says the table and motor are not included. That makes this a strong option if you already have a compatible table and motor setup, but it also means the purchase covers only the head. For a blindstitch task, this is the one that matches the work.
#### Industrial Sewing Machine Union Special 51-400 Double Needle Chain
This Union Special machine is set up for heavy duty double-needle chain stitching, which is why it belongs in a shop sewing jeans, trousers, and coats. It is an industrial machine with U.S. origin, and its double-needle role is the main reason to bring it in. The limitation is on the hemming side. If your main task is blindstitch hems on skirts or pants bottoms, a double-needle chain machine won't cover that job the way a blindstitch head will. For heavy seaming and double-needle work, this machine is a straightforward fit.
Final choice by use case
Choose the Consew 1099 CS-1H for blindstitch hemming on skirts and pants bottoms, especially if your shop already has a table and motor for the head. Choose the Union Special 51-400 for heavy double-needle chain seaming on jeans and coats. Let the stitch type decide first, then let your existing setup decide second.
