These people are more selling the apps and the "cloud" stuff than the hardware. If you want the hardware, go to eBay and look for an "ELM 327" - they have bluetooth, USB, and serial ones. I paid under $15 for mine, which is bluetooth. I use it to connect to the "Torque" app on my Android phone. No fancy "cloud," though, and it needs the phone to do anything.
