There are a lot of good options in the mid-sized tablet range, and if you're a fan of Samsung's designs, the Galaxy Tab Pro 8.4 is among the best. Right now you can grab a refurbished black model off of eBay for $199.99, a full $200 off of the retail price. Of course, it's not quite the latest model (that would be the Galaxy Tab S, with its AMOLED screen), so most retailers have it discounted, but it's still a fantastic deal.
The listing doesn't give any warranty details, but it does list the tablet as "manufacturer refurbished," which usually includes a 90-day policy. Standard shipping to the United States is free, and a variety of other countries can get in on the action.

The Galaxy Tab Pro 8.4 uses a 2560x1600 LCD screen, the highest resolution you can get at the size. The rest of the specs are pretty great as well, with an Exynos 5 processor, 2GB of RAM, an 8MP rear camera, and a MicroSD card slot. It's running Samsung's highly-customized version of Android 4.4, and it will probably get an over-the-air update to Lollipop. Probably. Eventually. If that's too vague for you, you can try out a CyanogenMod build.
At this price, these tablets are going quickly.
