Thermometer Advice?

I have the first accurite you posted and moisture got into the bottom and messed up the min/max temps. I don't keep my enclosures overly humid either.

I use these exact ones http://www.walmart.com/ip/Acu-Rite-I...ndingMethod=rr. I have been using for a year and have had no issues at all.

Thanks for all the input guys. :) I will probably head to Walmart tomorrow and pick up the suggested probed Acurite.
