reven: probably get something like these
Makita LXT618 18V Lithium-Ion Cordless 6-Tool Kit
KTL718C Hitachi 18v Lithium Ion 7 Tools Kit
though i may have to just get a dual set of power drills for the time being (I'm spending too much money on other house stuff ATM, network/nerd stuff :))
Looks like mine isn't on their list (they only list hammer drills and impacts). It was in the bunnings mailer which they appear to have taken down today.
