We own an Omnia oven and like it a lot. Even if you never use it for anything other then to bake pre-baked bread when there is no fresh bread to be bought where you are camping, it's well worth it in my opininon. Pre-baked bread also doesn't take long to bake in it. Proper meals take quite a bit more time (have a look at the recipes on their website) and I can't be bothered to leave the gas stove on for so long, having to stay inside the van and keep an eye on it. So we don't often use it for anything else.
