There's a flash sale going on right now at the mothership (for Prime members) foe what appears to be the same system for only $1 more. I did an online chat with ZModo and sent them links to both. He said the systems were functionally identical, but they were slightly different color/shape. The one at Amazon is a newer model. I just bought that one. $1 more for the newer version and 2-day shipping (with Prime, obviously).
