A few months ago I was looking at craigslist and found a SOS solar sport oven in new condition for $50. I had planned on building one just for grins but at $50, I couldn't buy the materials. Even though I had planned on using it camping, I start cooking with it to get use to it and never stopped. In fact I found a Global sun oven for $90 and picked it up too. I don't know how much money it has saved but I know I have only used our stove a few times. Cooking temps are more on the slow roasting range between 225 and 325 f, the chamber is sealed so food doesn't dry out or burn. That doesn't mean you can't over cook something, meat will cook down to mush if left in there long enough. Pretty much anything you can cook in a oven can be done as long as you adjust for the temp difference.
Most solar cookers use a oven approach except for parabolic and Fresnel, both of those allow you to cook as if you were using a stove top.
