Tanga offers the refurbished Ninja Kitchen System 1200, model no. BL700, for $84.99 plus $4.99 for shipping. That's $30 under the lowest total price we could find for a new unit. It includes a 72-oz. pitcher, 5-cup bowl with blade set, dough blade attachment, dough paddle, and three speeds.

A 1-year warranty applies, although it's unclear who supports it.
