Oppose, what do you mean by "indoor" grill. If you are referring to a grill pan, they are available at places like Linens 'n Things, Bed, Bath & Beyond, etc.
If you are looking for an electric grill, I would surf the Internet for sites that sell cookware/small appliances and see what's available there. I'm one for letting my "fingers do the walking."
