I would definitely go with good old American-made cast iron from Lodge. You can find their products in stores and on line, but since they're so heavy, shipping can add a lot to the price. Cast iron is an excellent conductor of heat, won't warp and will last a lifetime. I treasure my pieces of cast iron! If I was told that I could only keep certain things in my kitchen, my cast iron pots and pans, plus my Henckel knife set would be at the top of the list.
Just to give you another idea though...I find I use my electric pancake griddle a LOT for things like you mentioned. We have an island in our kitchen and I just plug it in there and we have an instant breakfast bar with pancakes, bacon, eggs...you name it. We also use it quite a bit for grilled sandwiches as well as warming up tortillas. I bet you can find one for a fairly reasonable cost ($20?) or spend quite a bit more for a really fancy one! We use ours frequently and the non-stick lasts about 5 years before we have to buy a new one. I don't think that's too bad.
So I hope that helped. Have fun shopping!
(I got a new, bright red crock pot for $18 today! That's my Christmas present to myself!)
