igrill bluetooth remote thermometer $59.25 FS
AT&T has the igrill black or white for $59.25 Free shipping This is the best deal that I could find. Next closest non ebay item was about $70. There are a couple used ones that might go cheaper, but my experience with grill thermometers is that you will use the warranty, so buy new. I have had many of the temp probes go bad on my Maverick. I use my smoker all the time and this is useful for those overnight smokes so I can just check the temp in my ipad without getting out of bed.
