I have a cheap food dehydrator (ronco) that works ok. Drying is very
uneven depending on the location of the food. I have to turn the trays
and switch them around several times though a drying cycle.

I have seem some dehydrators advertised with "forced air", where a fan
circulates the warm air. They claim the results are more even with no
need to be switching around trays. Does anyone know if these really wotk
better? I think the one I saw was American Harvester.

Thanks,
MK
