[nabentre] Using Pricing Guns

[JumDrum]

     Hi list,
  Does anyone have experience using a pricing gun?

  I manage a very small church associated health food store, which sells frozen and canned items.
  Prices for frozen items are posted in a list, while cans are priced by a sighted volunteer using a magic marker.
  But I want a solution for when a "pair of eyes" isn't available.

  Before I start shopping for a pricing gun, does anyone have a recommendation?

  TIA.
