I'm one of the PilotAware development team.
I don't know why you think it's not a professional solution, it has moved on from when it was a kit, and the full unit is now available from the website above.
I agree, back in the EARLY days of the beta unit you had to solder things together yourself. Those days are long gone.
It's all CE tested now etc.
The original website for the home building beta testers is being rewritten as we speak, and the official hardware outlet is now open and it's being manufactured. There are over 500 units out there right now.
I only mentioned it as the discussion had turned to which external GPS to use for an iPad and SD, and it makes sense to use a PilotAware for GPS AND you'll get traffic.
It's a no brainer at the price, but I would say that wouldn't I ?!
