I have seen play-asia run out of stock a few times.
Maybe the flood of android devices sales are obscuring the caanoo?
Last time I heard they are still in production.
For one funny fact, they sell really quick.
Caanoos arrive here in batches of 10 - 20 units and are usually sold through Mercado Livre (brazilian e-bay sort of thing).
They usually least a couple week.
Edit:
like you can see here:

I bought mine this way and ended up paying a little more.
But importing such thing, even from play-asia is a tax loterry kind of thing...
government may charge 100% taxes on final price plus hold it for a few months.
I take this guy gets his caanoos from an e-bay girl reseller and a few other sources.
He is a nice chap and his price is in between the original and half a fully taxed one.
I got mine the day I payed, wen´t to pick it up personally
