When assessing the price, you must look at the number of heads (1 to 20+) and the number of needles (usually 9, 12, or 15) per head. A higher needle count allows for more complex multi-color designs without manual thread changes. Additionally, verify the maximum embroidery speed (RPM); high-speed models reaching 1000-1200 RPM command a premium but significantly increase production efficiency. Ensure the machine includes a Dahao computerized control system, which is the industry standard for Feiya machines, ensuring stability and ease of pattern uploading via USB or LAN.
