For anyone outfitting a workshop with textile apparel machinery, the choice between a ready-to-run industrial head and a specialized one can be stressful. The Singer 31-15 is a complete package; the Singer 151w3 is a head for people who already have the rest.
Quick Verdict
If your priority is to sit down and sew common fabrics immediately, the Singer 31-15 with table at USD 180.00 is the clear choice. If your work focuses on specialty materials and you already have the rest of the setup, the Singer 151w3 at USD 265.00 is worth the extra spend.

Where Each Product Wins
- The Singer 31-15 wins if you want a working machine as-is. It was in use until the previous business lost its lease, and it includes a 1/4 HP GE motor and a few extras. You can start sewing right away.
- The Singer 151w3 wins when material handling consistency matters. That capability is useful for layered projects that can slide between layers of fabric.
Product Notes
Singer 31-15 with Table
This listing is a working vintage Singer 31-15 with a GE 1/4 HP, 115-volt single-phase motor. The machine was still in use until a couple of months ago, which makes it a realistic candidate for someone who wants to start sewing quickly. It also includes a few extras such as needles. The 31-15 is a straight lockstitch, single-needle machine with a maximum speed of 2,200 stitches per minute and a presser foot clearance of 5/16 inch, so it suits medium-weight fabrics. The catch is that this is a straight-stitch-only model, so if your work needs zigzag or decorative stitches, this machine won't cover it.
Singer 151w3 Head
The Singer 151w3 here is a head-only vintage machine. It is a small walking-foot, one-needle, medium-weight lockstitch machine used for material and light leather, as well as denim, vinyl, and similar items. The walking foot is the key differentiator here: it helps presser foot feed the material evenly, which matters when you're sewing layers that tend to slide. The head uses 135x1 needles and mechanical control. The limitation is that it may need additional cleaning, since it comes from surplus stock.
Final Choice by Use Case
Choose the Singer 31-15 if you want a lower-cost, complete single-needle setup for tailoring and everyday medium fabric work. You can get it running right away.
Choose the Singer 151w3 if your projects lean toward specialty materials and you already have the supporting setup. You'll pay more for the head, but you're paying for a system designed for layered work.
