Another Canberran, nice! It's amazing how similar your post is to my first one, check it out: http://www.ozmpsclub.com/forum/new-m...-canberra.html
I had the same opinion of the WRX and went for the MPS for the same reasons you did.
Mine arrives within a couple of weeks. I'm getting mine from Slaven in Phillip, the service there has been second to none and I recommend you talk to them (likely you already have).
It should be noted that if you get a Black one, you'll be in with all the cool kids.
