Other World Computing offers the used Apple Keyboard Dock for iPad, model no. MC533LL/A, for $27.99 plus $5.79 for shipping. That’s tied with last month’s mention and $6 below the lowest total price we could find for a refurbished unit. (For further comparison, new units cost $60 more.) This dock features a rear 30-pin connector and audio jack.

Note: A 90-Day OWC warranty applies.
