I have built a couple of DIY solar ovens from cardboard and aluminum foil like this one called the CooKit. They actually worked pretty well, but were not very durable. I have been contemplating the purchase of a SOS Sport Solar Oven. They cost $135 + $39 for shipping. I am a big bbq enthusiast, but in the interest of becoming more "green" I think I could have a lot of fun cooking with solar ovens instead of charcoal. It's healthier as well.
Has anyone found a better solar oven than the SOS Sport for the money from a bang for the buck perspective?
I am interested in other suggestions / perspectives.
