The LG G4 came out roughly a year ago, and it was a rather nice phone, all things considered. The price started out up in the standard flagship range, but it has come down considerably. Now, you can pick up a new-ish G4 on eBay for $200. That's a solid deal.
This is listed as "New other" condition, which means the phone is unused and comes in a generic box. The charger will be a third-party (probably crappy) unit as well. It's not like you don't have other microUSB cables around, right? Other sellers would probably call this "open box."
The H811 model is the T-Mobile US variant, but it's unlocked. You'll get full LTE support on T-Mobile and compatible MVNOs. It doesn't have all of AT&T's bands, but it'll work. You have your choice of the leather back or gray patterned one. The $199.99 asking price includes free US shipping. Tax is paid only in New York.
The same listing now has the G4 even cheaper. You can pick this phone up for $179.99 right now. It's not the latest and greatest anymore, but at that price I imagine stock won't last long.
