Google recently reduced the price for a Nexus 6 phone. Now it's $499 for the 32 GB model, $549 for the 64 GB model. I didn't see an offer to allow you to pay in installments.

The Nexus 6 was introduced in October 2014. The phone still has up-to-date specs, running the Qualcomm Snapdragon 805 processor. The Nexus 6 camera has received positive reviews (e.g., http://connect.dpreview.com/post/7285707615/dpreview-recommends-best-smartphone-cameras)
If you're not sure about a phone with a six-inch screen, then you might want to wait until Fall. Google is expected to announce a smaller Nexus phone from LG or Huawei, perhaps both. These new models will work with Google Fi.
