There's a discount shop in Grafton NSW (its like the newer version of CopperArt...they sell mid price range stuff)...anyway, they have had dehydrators recently (on more than one occasion) for $35! These ones even have the different temperature settings so they can do low temp herbs etc, and higher temp jerky. I bought the you beaut "ezi dry snack maker" (I think) but really, I would've gone with this "cheaper" model myself it had been around when I was looking! My friend also bought a similarly priced one from Aldi, and she is equally as pleased with it, for her it suits her purposes.
I'll post the name (and PM it to you) when I go past the shop soon.
