The shopping cart is down right now, so I can't tell how much it is. How much is it?
I see a GSM 850/1900 version is coming but even the 900/1800/1900 tempts me a bit.

GSM 1900 coverage here in Canada is reasonable. There are no sites here that are GSM 850 only.
CA: SaskTel, Wind postpaid; Rogers, Bell postpaid iPad flex plans; US: T-Mobile postpaid data, prepaid voice; PureTalk (AT&T MVNO) prepaid voice/data; AT&T prepaid iPad plan
Hardware: Too much but notably iPhone 5, iPad Mini Retina LTE, Moto G LTE (N.A. version), iPhone 4. All unlocked.
