Tanga offers the factory-refurbished Sling Media Slingbox M2 Set-Top Box, model no. SB375-100, for $69.99 with free shipping. That's tied with our November mention and $25 less than the best total price we could find for a new one. It enables you to stream cable, satellite channels, or DVR to your device or television. A 90-day Sling warranty applies.
