Temp Overheat Gauge with Alarm

Hi all.

I've search a bit, and have not run into a general recommendations/how to for rigging up a more accurate temp gauge with some type of alarm.

So here are a few questions, to get things started....assuming other folks are interested-

I have found a few temp gauges with alarms online. Has anyone used any of these (see links below), or does anyone have any other recommendations?

The Mason alarm seem great, but I contacted Dave Mason and he no longer makes them as demand fell away about 3 years ago.

Or....has anyone rigged up something different, and if so would they be willing to share the process. I would be willing to be a guinea pig and document my install and post it, but I would definitely need some help as I generally have no idea how.

Thanks!
Matt
