I've got a $100 Macy's gift cert burning a hole in my pocket and am wondering if a grill pan might be in my future. I do have an old over-the-gas-burner grill (the kind where you put water into the sides of the holder, then place the grill into it), but it's a real pain to wash and I wouldn't mind investing in something newer and easier to clean (but doesn't have to be dishwasher-safe). I'm willing to supplement beyond the $100.
Le Creusest? Calphalon? Something else? Non-stick or not? Round? Rectangular? All advice gratefully appreciated!
