Landarc, I don't have a thermo I can read from outside. I bought an oven thermo at BBQ's Galore that sits on the grate. I've found that the temp on the cheap thermometer that is on my lid consistently reads 55 degrees cooler than the actual grill.
I saw a grate thermometer that you can read from the outside, with two prongs at Target the other night on sale for $10... Is it just a waste of money to buy such a cheap one?
