Old one with no temperature setting. Doesn't get near hot enough. Meats cooked on it are the complete opposite of the "the fat runs off" spout and are greasy as heck.
Hamburgers, terrible for. All hamburgers taste like is grease. Steaks, forget about it, not going to ruin a steak by not grilling on a VERY hot grill. Perhaps for chicken breast it would work well. Pork chops already mentioned, I don't know. We do the season thing in the bag and bake them.
It is faster and far less of a pain to just fire up the gas grill. I grill all year. If wifey wants hamburgers, she lets me know that I am cooking that night and I fire up the grill. Only takes a few minutes to heat up and clean, then a few minutes to cook. The cleaning comes easy before cooking after it is heated up as opposed to trying to clean between all those little non-stick surface channels with something that won't ruin it after cooking.
My wife does the baked food and I do the grilled food. The George Foreman just takes up space in one of the kitchen cabinets.
Oh wait! Bacon! It does works great for bacon! Much easier than having bacon grease splattering around in a pan on the stove. Wifey likes bacon in the microwave, I like mine the old way frying in a pan. Bacon is the ONLY thing I've found the George Foreman half decent for.
