If you don't want to be a slave to your grill a barbecue timer is a good tool to have on hand. This way you can set the timer and get back to reading your book or playing with the kids until your steak is ready to turn. Grill timers cost between $5 and $25 online. Cheaper grill timers are simple plastic dial timers while more expensive grill timers can have digital features or be combined with a thermometer option. Grill timer/thermometer combos allow you to time your grilled item and take temperatures with a pronged tip.
