Is there a stainless steel fireplace insert conversion for my home?

I have a traditional brick firebox with gl doors in my home. The previous owner built a horrible looking pink marble surround which I want to tear out. What I would ideally like is a very modern looking fireplace opening like the one seen on the red wall here: http://www.fireplaces-store.com/. Fuel type is not an issue because we will hardly ever use it as a true fireplace. However, it may be too difficult to pipe in natural gas, so that may not be an option. Just looking for a good retrofit into my existing firebox.
