I have the VBM and a Macap M4D, and it is a great combo.
Do not short-change yourself on a grinder--it is as important, if not more important, than the machine.
That said, the MM or the K3T are good grinders, it all depends on your budget as well.
Most of the sponsors have prices on their web-sites.
I can recommend talking to Chris at Talk Coffee, he was most helpful to me.
I havent found a place in Adelaide with a good selection of grinders on-hand, although The Coffee Barun will order in almost anything you want.
