As someone who's owned two GB Premiums, my vote goes to that. Yes it's a lot for one pin, but while I love the artwork on the Pro, the extra features on the premium are well worth it IMO.
My GF loves GB and so do the kids. It's fun, beautiful and feature rich. I would not recommend a NIB either way. The secondary market has some good GB options now so save yourself the money. I do know of a GB Pro going up for sale soon in IN (I think) if you decide to go that route. PM me if you want the details.
