If your talking about the mustard colored one, it is not an oven. It's just a rangetop on metal legs with a splashguard type apron. I've been fooled by that one also. I think if they have stand-alone rangetops they should also have built in double ovens.
No, I mean the white one with the black oven rings on the top, called the Elegant Chef Flamebay Gas Range (costs $900). I haven't tried any of the other ones apart from the ShinyTyme Cooktop (the stand-alone gas range thingy). I agree they should have built-in ovens, otherwise they should just make it so you can put gas rings on a countertop. Would be a lot less confusing
