Temp gauge?

[nate]

What temps gauges are you guys using?

I notice there are two on OSE, but the O'donnell Temp looks better than the Duratrax...

I went ahead and got the Duratrax temp...

Are they ok?...

I have a duratrax works just fine. I am sure it isn't ac acurate as the way more expensive ones but it is within a few degrees for sure.
