I have a similar super old one with an aluminum tub and I'm worried that it's becoming a significant source of aluminum in my diet. Are there any options besides aluminum and teflon? I'd really like one with a stainless steel interior.

Aluminium will produce a thin layer of aluminium oxide to coat the surface. This layer is extremely strong. So don't worry about aluminium in your diet. Whatever you do, don't switch over to non stick. Those Teflon will end up in your rice eventually.

The tub on mine is definitely corroding. The oxide layer does not protect aluminum from corrosion forever.
