Carbatec (Brisbane) are selling the Porta Cable Finish Nailer DA250A out for $319 (where $411)!!! I believe this is due to the new model which is a bit lighter and has the mag repositioned.

I bought one yesterday (been drooling over it for months) and it is a great unit. Finished a small fence for SHMBO in two hours not the 10 it was gunna take due to the nails bending in the hardwood rails! Anyway, check it out if you are in the market for a Nailer.
