Anybody have one of these? I am about to buy one
and test the RX8.

Don't have one, Paul...but it looks very interesting!  Which model are
you planning on getting:

Prices range from $139 to $219 there at Davis, depending on model
(available logging time, alarms, and software reports... personal or
fleet).

But, a quick check around the internet finds some considerably lower
prices, as well...

There are a few available at Amazon.com as well.

I am going to get the E/X with the 25 engine parameters and one second
sample time.
I don't need the alarms. I want to monitor the mixture ratio
as a function of engine temperature during start up.
