You linked an $8,500 package originally. I was quoted $9,000 delivered for Z&B 6 burner (double hood) + fridge + sink. I think they're similarly priced, obviously that quote doesn't include the drawer module, but that's what, $1k?
They're all going to cook meat. You're paying for SS and a sleek, uniform look. If you find a full kit that looks as good as either for sub 7k, let me know and I'll buy one ;)
In Bendigo I have seen the package that I linked for much, much less than $8,500 at a number of retailers.
