If it were me, I would wait until he (or Schneider) gets traded, or at least until the trade deadline.
When he's secured a starting job, that's when he'll be most valuable. Although I do recognize he's playing well right now.
As for what you could get... Right now, I think maybe Getzlaf... Skinner.... Eberle maaaybe.... Yakupov.... Shattenkirk maaaybe.... You know, it depends if the other guy needs a goalie too. If the other guys has Niemi, Lundqvist, Quick and Anderson already, he probably doesn't need Luongo.
