Ontopic: If you actually want one of these grills, some nice features to look for:
On off switch (cheaper models don't got one and you HAVE TO unplug it/plug it cause it gets hot)
Higher wattage: Cheap models take forever to get meat to a safe temp to kill salmonila/e-coli and don't brown well so you get dry meat.
Size: The smallest can really only do one burger at a time (e.g the model you can track down for $20)
