You've chosen a bad time to start looking for Apple II equipment - we've been seeing early Apple's selling for multiple thousands overseas recently. Hopefully this will settle down and you'll be able to find what you want at a reasonable price soon
If getting the earlier models is not a concern for you then you should be able to find an Apple IIe at reasonable price - I got a IIe Platinum with monitor recently for under $100. You can post on the Wanted board here, and keep an eye on TradeMe and Sella.
I'm pleased to hear that you're after something working and usable rather than mint and "collectable"; that's always been what I've looked for as well, though I've tended to grad a nice example when I see one at the right price.
