Adorama offers the Tascam 4-Channel Audio Recorder for DSLR Cameras, model no. DR-70D, for $199.99. This $30 mail-in rebate drops it to $169.99. With free shipping, that's $10 below our September mention and the lowest total price we've seen. (It's the best deal now by $55.) It features a 20Hz to 20kHz frequency response, four XLR/TRS inputs, micro-B USB 2.0 port, and two integrated microphones. Rebate ends December 3.
