Microwave or Oven?

I've noticed some saying that you can have them replace the built-in oven with a microwave at the factory when you are ordering your TM.

Just wondering what people's thoughts are on this. If you have the oven, do you find it useful? Does it work well?

I'm thinking I'd rather bring a small toaster oven along than a microwave. Seems like it would be easier.

We will be mostly camping in campgrounds with elec. if that has any bearing on recommendations.

Also - I hope no one is bothered by the flurry of posts. It just seemed like it would be more helpful to others if I separated my questions out with descript titles than having one post with all my questions.

Thanks for all your help!
