Advice on a temporary android phone

My iPhone 6 had its antenna break and is now essentially an iPod. I am trying to wait it out for the release of the iPhone 8 and figured I would try out the android platform on a cheap temporary phone in the meantime. I'm looking to spend under $150, I don't care if it is used, I live in the US and have Sprint as my carrier. I've glanced at the LG G3 and found one for $88 but haven't found much else. I really don't know what's out there for android phones. Any advice?
