Be careful with discontinued binding machines because replacement parts, dies, manuals, and matching supplies may be harder to find over time. A discontinued machine can still be useful if your office already uses that binding style and only needs matching information, support details, or a replacement path. For a new setup, choose an active machine style so supply availability and support are easier to manage. If you are comparing an older machine with a current model, check punch pattern, punch capacity, bind capacity, manual or electric operation, and whether the dies are fixed or disengageable. The best choice is the one your team can support long term.
