Right now you can pick up a refurbished Nexus 6 from eBay for just $180. While not being new units, the condition is listed as excellent and they shouldn't show signs of wear and usage. If you are looking for a great deal on an Android N-ready phone, this may be the deal for you.
Sure, it isn't the latest and greatest, and doesn't have a fingerprint sensor, but it still is quite the deal. If you are interested you should act quickly, as we have no idea how long these will remain available. Currently, only the black version is available.
Newer model: Nexus 6P
