As if deciding which Nexus device to purchase wasn't hard enough, there are also several other killer Android flagships that are getting cheaper by the day, begging consideration. One of the best of this group is the LG G4. Just a month ago it was available for $400, a great price, and now you can pick one up on eBay even cheaper at just $380.
The model in question is the H815 variant, which works or most of AT&T's bands and should also be good for use on T-Mobile, if you are OK with not having access to band 12 (also remember that HSPA+ will only work in areas with 1900Mhz towers). It's available in plastic shades of grey and gold, or, with a handsome brown leather back.
The device ships free and sales tax will only be charged to buyers in the state of Florida. The seller is also willing to ship to a couple dozen other countries listed in the item description, but be prepared to pay steep shipping rates and import charges.
