Well thanks to everyone for offering me their wonderful advice and the GF670w has finally arrived safe and out and works right out of the box. It feel solid,not as solid as the yashica mind you, but strong enough for my needs and not like some other flimsy medium format camera in the same weight category.
The deal was pretty good that I was worried it was a scam only when I won the bid. But the seller was genuine and given threw in 2 rolls of Velvia 100 into the package free of charge! I kinda feel guilty thinking it was a possible scam.
So I loaded a roll portra 160 and went out shooting. Hopefully I'll be skilled enough to take wonderful pictures with this camera.
