We're using these in our scan tools:

Sparkfun took the same module, and created their own breakout box:

In turn, we developed a similar board with the same pinout, and added three 
LEDs (Tx/Rx/Status) to make it interesting. We went as far as building a 
prototype, but the project was put on hold due to lack of interest. I can 
post the schematics/board layout if anyone is interested.

My question is, at what price point would a module like that become 
attractive to hobbyists?
