Two used industrial sewing heads look similar at a glance: both are mechanical, both are sold head only, and both fit into textile and apparel machinery work. But they are not interchangeable. The CONSEW 1099 CS-1H is a one-needle chain-stitch blindstitch head for garment hems. The Singer 151w3 is a single-needle lockstitch head for medium-weight material and light leather. Your choice should come down to the work you feed the machine, not which one is cheaper.
Quick verdict
If your regular jobs include skirt hems, pants bottoms, or other areas that need a tidy blindstitch finish, the CONSEW head is the better fit. If you mostly sew material that needs even-feed control, the Singer is the better fit.

Where each product wins
The CONSEW 1099 CS-1H wins when blindstitching is the core job. The one-needle chain-stitch blindstitch action is made for skirt hems and pants bottoms, and the included knee lifter lever helps with positioning. The Singer 151w3 wins when you want a walking-foot lockstitch that feeds layers evenly; it is $34 less, and the lockstitch design is the practical choice for the same material range.
CONSEW 1099 CS-1H Blindstitch Head
The CONSEW 1099 CS-1H is dedicated to blindstitching, and its one-needle chain-stitch action is the reason to pick it for skirt hems and pants bottoms. It is a used mechanical industrial head made in Japan, and a knee lifter lever is included. This is a later-model machine. If blind hemming shows up in almost every batch, this head does exactly that task. Its limitation is specialization: it is not a general-purpose seamer, and if flat seaming is your main work, the blindstitch action will not help you.
Singer 151w3 Walking-Foot Head
The Singer 151w3 is a vintage single-needle lockstitch machine with a small walking foot. It is suited to medium-weight material and light leather, and it handles denim and vinyl as well. It uses 135x1 needles. The head comes from surplus stock and is described as complete and in good condition, though it may need additional cleaning before you start using it. That is a reasonable expectation for a vintage industrial head. The limitation is the other side of its specialty: this is not a blindstitch machine, so invisible hems on pants or skirts are outside its range.
Final choice by use case
Pick the CONSEW 1099 CS-1H when blindstitching is a regular part of your workload and you want a head already set up for that exact stitch. Pick the Singer 151w3 when you need even-feed control on the jobs it was built for. Both are head-only units, so you will supply the table and motor. Once the head matches the work, the right choice is simple.
