It looks like Cuisinart has on with stainless interior- but some reviews say very noisy... {amazon reviews}

If you get a micro/convection.. those usually have stainless interiors and it looks like prices have come down from a few ears ago.

there are some good review sites that might help you find what you are looking for, but not many tell what the interior is...
