I routinely use an ordinary heating pad from the drugstore to start my tomato & pepper seedlings. I cover it with aluminum foil to prevent accidental contact with water, turn it on low or medium setting and set the seedling flats directly on the pad. I fully agree-- there's NO need to purchase expensive & special heating pads for starting seedlings.
