There aren't a lot of options for big tablets with styluses, so the Samsung Galaxy Note Pro 12.2 is kind of the automatic winner. The only problem is it's so darn expensive. Well, unless you're down with a refurb. You can pick one of those up on eBay right now for the reasonable price of $389.99.
The Galaxy Note Pro 12.2 has a 2560x1600 LCD screen with support for the pressure-sensitive S Pen. Inside it's packing an Exynos 5 Octa, 3GB of RAM, and 32GB of storage. This is a refurbished device, so it was returned to Samsung at some point for a defect or because of buyer's remorse. It's usually a $650 device, so the discount is rather good.
The deal includes free shipping in the US and tax only in New Jersey and New York. The seller will ship to a few other countries, but it's pricey.
