As an owner of the FX-888, I strongly recommend it. (even though I did not like the "toy" look at the beginning). I just make sure I turn it off when not in use for a while to prolong the life of the tip. It heats up really quick, and holds it temperature quite well.
Why not get it from our friendly hosts (http://www.adafruit.com/products/303
)? @$95 bucks, and with great customer service, it's hard to beat.
Taxes and duties are usually limited to GST (I am in Quebec) when shipping with USPS/Canada Post. Sometimes they charge you an extra $5 for expedited customs service if you request expedited USPS.
I've had bad experiences with UPS & duty charges, though, so I wouldn't go that way. I've had good luck with FedEX.
