I am going to add the thermometers to the lid at the grill level. Is there a decent recommended brand of thermometer? I've looked for a Taylor 814 model but cant find it anwhere except on their website. I've also noticed that a few of the pictures I've seen look like poeple use a couple of digital probes poked through some sort of weight (looked like a potato). Does that work? Wouldn't see why not. I just dont want to start drilling a bunch of holes if it is not necessary. Thanks in advance!
