My son has been saving up for a couple of years with the goal of getting himself a Lego Mindstorms EV3, and I'm wondering if anyone knows a good (and potentially cheap) source to get one from locally.  I've considered Amazon and Youshop, but Customs fees and GST would wipe out any savings.  They're horrifically expensive.

At this point, given the exchange rate it may be worth trying to buy one in Australia.
