Z30 purchase decision. Which carrier, which store?

What option should I go with?
Buy unlocked $299 and go to AT&T?
Go to Verizon 2 year plan for $199?
Go thru Amazon for 2 year Verizon plan for $99?

Currently with Sprint Q10

Surely, that's your choice and your choice only.

"Z30 STA100-2 UK" 10.2.1.3442 Get's a Ten from Fen.

I would base my carrier choice on who offers the best coverage in my area first, cause how much doesn't matter, if you can't use the dang thing.

I'm on Version with a Z30.
I like the coverage, speed, and the extra that the Verizon brand Z30 has of the built in QI charger.

As you are on Sprint, I would check to see if they will let you bring a Z30, you can buy them from BlackBerry outright and unlocked, to roll into your current plan.
Otherwise ask others in your area what carrier they use and how's the coverage to get an idea on what carrier may be best for you.
