Recommendation for a digital thermometer?

[echoDreamz]

Does anyone have any recommendations for a good digital thermometer? The cheap petco zoomed one I have is off its rocker. Shows 83.4F when the good ol' fashioned one shows 76 - 78F.

I've replaced the battery, no luck.

I have a cora-life
I like it because it can be calibrated
it also has a low/high temp alarm
bought it at petco was like $32.
