Dehydrator recommendations?

[Guest guest]

I am wanting to make my own gluten-free crackers out of ground seeds and

do some other food projects that involve a dehydrator. I know that most raw

foodists recommend Excalibur brand dehydrators, but I understand they are

made of polycarbonate with teflex trays and I'm a bit nervous about making food

and possibly adding toxins into it, since 1) they will be wet when they go

in the dehydrator and 2) there will be heat inside the dehydrator

I was considering looking at a stainless steel variety as an alternative but they

seem to be a lot more expensive. I am wondering if anyone on this list has

some suggestions. One thing that has been suggested is to line the teflex trays

with parchment paper in a polycarbonate dehydrator, but I don't know if that really

does the job to avoid any toxins from the polycarbonate (BPA) that could leach into

the food somehow.

Does anyone have any experience with this?
