Double wand wielding from complete arcane or races of eberron one or the other allows a blastificer more power if they can make wands cheaply since it allows essentially duel wands. Problems is it requires two weapon fighting and what might be a problem craft wands.
There were new infusions released in Races of Eberron, and WF artificer substitution levels for if you are playing a WF artificer.
