I have heard of a temp guage that will beep u (or something) when thenmeat temp is right. That's good if only not to have to open egg to read temp of meat. what would be really nice would be a combo temp gauge to notify u of the meat temp and the dome temp. I haven't learned to control it too well and practically stand next to it for 30 min or more verifying temp it working right. any inventers out there?
