But wait! Thanks to the magic of miracles, (magnets, you philistine!) there are other options!
InfiniApps makes a universal and brand-agnostic magnetic holder with the oft-questioned CD-slot mount. They're fairly cheap, very reliable, and have been through five incarnations of redesigns. The latest of which holds well in all sizes of disk slots, doesn't break at the neck, and most importantly to us, has FOUR strong magnets in the mount face to hold even our heavy Betty, chubby tubby, plus sizer, wide load, is this joke dead yet, Note 3.
Because the S-Pen appears to use at least a partially magnetic sensor for the hover function, it will be inaccurate (though within 5mm) with the S-Pen whilst mounted to any magnetic mount. Finger touches are entirely unaffected of course, as is the S-Pen when not currently on the mount itself.
The mount comes with two steel plates, one with adhesive, one without. Both plates have one side coated with a thin plastic scratch prevention film. I use the adhesived plate on the inside of the back cover, though you could just as easily do the same on the outside or use the adhesive-free plate and just let it sit inside. It doesn't pull the back cover off or cause any cosmetic distortion of the device.
Amazon is always a good way to go for reliability and shipping speed.

*deep breath* whew, mouthful!
Price-wise, however, is another matter. Meritline.com is a long-running and reliable Chinese import company. They have warehouses on the west coast for their most popular items, but mostly ship from China. If you don't mind a two-to-four-week wait, you can get a lot of stuff at a heavily discounted rate. Meritline's usual prices are generally the same or just under Amazon's but then you get their Daily Deals.

Long title writers, stahp!
Today, and several times a month, the normally $25 mount is discounted with a coupon code. MLCQ13RN (as of 1/13) in the shopping cart gets you eight (count em, 8!) bucks off, for a $17 final price tag, including free shipping. That's almost half what Amazon's ticketing the same item at. Both sellers are selling the same Generation 2, Version 2, reinforced-neck, stronger-magnetic-head item. The choice, if you want the thing, is up to you whether you go for 2-day free shipping and a higher cost or the longer wait and cheaper price tag.
I've used this exact mount for a month now (and two of the previous incarnations for over a year) without a hitch. I picked up the prior Generation 2 mount with the weaker neck from Amazon, it broke in a week, and they replaced it with nary a fudge with the new version. I've shopped with Meritline.com for half a decade and their customer service is genuinely on par with Amazon. Break something or have another issue, snap a photo of the damaged goods, and they've never failed to replace or refund the purchase.
