That is a good deal. I think the Dot 2 is the best bang for the buck among the Echo, Tap, and Dot. I assume the same when you consider the two new devices as well--the Show and the Look.

BTW, I still haven't heard any specs for the screen on the Show. I'm assuming it will be low resolution at perhaps 1024 x 600 px just like the new Fire 7" model.
