Please try to include example model name, approximate price (maybe Allegro link or similar) and a short explanation why we need it.

Justification: to produce things out of sheet metal - boxes, pans, trays, enclosures etc.
Features: Minimal working width 1m. Ideally would be magnetically clamped model like Magnabend (description and diy instructions - http://aaybee.com.au/Magnabend/Magnabend_Homepage.html) but any traditinal one would do.
