VerdictSpecs checked against Singer data · Checked Sep 2026
6.8/106.8
out of 10
The middle Singer Heavy Duty: the 4423's head with 32 stitches, and the 4452's head without the accessory pack.
Who it's for
Beginners who want more stretch and decorative stitches than the 4423 and do not need the 4452's walking foot right away.
Skip it if
You already know you want a walking foot, in which case the 4452 pack is usually cheaper than buying one separately.

Check before you buy
3 checks01
Price it against the 4452If the 4452 is within $20 to $30, its walking foot and nonstick foot alone cover the difference.
02
Color and edition listingsSinger sells black and special edition 4432 variants at different prices. Confirm the stitch count is 32 and the head is the same before paying for a color.
03
Confirm weight for portabilitySome listings show 17.4 lb, which appears to be shipping weight. Ask the dealer for machine weight if you carry it to class.
