In my own opinion I find a VPN between the two offices to be a better choice because in the long term it will be cheaper. The internet is a powerful too that has already been built for us, why not use it. To have redundacy between the two locations, create a DDR link from one router to the other using a leased line or ISDN. I am proponent of cisco products, so that would be my recommendation for the routers and VPN solution.
