Brother PT-2730VP on sale today for $47.99. Its definitely one of the more feature rich label printers, and the highest end one that I've seen for a while that is being sold for such a low price.

Normally sold for over $100 without the case. The VP designation means that a case is included. I've owned a number of brother label printers over the years, and the main issue that I have with them is that there is quite a lot of lead in and wasted label space if you were printing one label at a time.

Still, they make fantastic label printers. I have one that I've printed hundreds of labels that is still going strong. An AC Adapter is included with this unit, but batteries are optional (just standard AA sized).
