Seeing the website and trying the product are two different things. In response to one of your original questions, the TWS/RWS is probably your best option. The board is moderately-sized, so there's no need for surface-mount soldering. The range is very consistant--even in fog or light rain. The mechanics are very easy to use: binary goes in, radio comes out, and vice versa. And it's the cheapest embedded transmitter/receiver for that band on the market (as far as I know).
