Andy,

Genuinely glad you are happy.

I cant see how anyone can make money on 25 units and cheaper
than the CURRENT secs monitor unless its all done for love.
I am not a charity so good luck to "them"

This is why the new unit I have made it multi purpose/multicar and
has the facility for extra external sensors and data logging to a PC
and also has a larger display than the current secs monitor
but wont cost much more at all but I hope to sell a fair few
to recoup my development costs.
Pictures have already been posted elsewhere so wont repeat them here.
