Amazon offers Prime members the Dymo LabelManager 160 Hand Held Label Maker, model no. 1790415, for $9.99 with free shipping. (Non-members can spend $35 or more to qualify for free shipping, otherwise it adds $6.93.) That's the lowest total price we could find by $15, outside of our mention below. (However, it was $2 less via pickup a month ago.) It features 195 symbols and clipart; computer-style keyboard; LCD display; and uses Dymo D1 labels in 1/4", 3/8", 1/2" widths. It requires six AAA batteries (not included).

Don't mind picking it up? Office Depot and OfficeMax offers it for $9.99 with in-store pickup.
