MiWi Products (Score 1)

In addition to selling ZigBee chips, Microchip also supports an even simpler protocol called MiWi. I have looked into using this for my around-the-house electronics projects, but a board with MiWi and all of the components (caps, resistors, etc) costs around $30 bucks from Microchip. This could get expensive if you plan on using this to control many lights, a/c, etc around the house. The chips are actually cheap (around $2), but when you want all of the circuitry that make the chips work on a PCB, it gets more expensive. I just want something that I can pretty much send and receive data to/from without having to do all of that soldering. Does anyone know of some cheaper options?
