The Nexus 9 is a good tablet, but the price is a little high for what you get. You know what isn't priced high? Refurbished 2013 Nexus 7s. A cache of these tablets makes an appearance every now and then, and you can get one today on eBay for just $139.95.
This is the 16GB version, sure, but for the price you can't really argue. The Nexus 7 packs a Snapdragon S4 Pro, 2GB of RAM, and a 1920x1200 LCD. Since this is a Nexus tablet, you should have an update to Android 5.0 Lollipop waiting for you out of the box. Note, these are tablets that have been refurbished by the seller, not Asus. If you're feeling weird about that, you have through January 31st 2015 to request a return.
As usual, this deal includes free shipping in the US, and tax is only paid in New York. International shipping is offered, but it'll cost you.
