I have a Hobby Boards Lightning detector, but it is a simple device and only counts events. It works great for what it is, but there is no direction/range capability for it.
The Boltek seems to be the standard for detection, direction and range. Unfortunately, it is more than I can justify cost wise.
I am wondering if there are others that would like to encourage AcuRite to make a affordable lightning detector that would give some range and distance capabilities.
