Go with the MavMount, well worth the price. I find it is actually well balanced with the iPad Mini and the combo is light enough that it is comfortable to hold and hangs securely from the lanyard. The clamp also works with various cases. I use a thin silicone one with the Apple magnetic cover and it holds it nice and tight. Use the XL clamp as it holds the tablet a little higher. I think the lanyard is a must with the mini or other small tablet/phone, but if you use a larger tablet (I used the Pro 12.9 for a bit) it is just too heavy around your neck and **** awkward to boot. With the mini you can also pick up a shorter lightning cable with the right angle connector to plug into the RC without a lot of excess cable dangling.
Let me know if you are interested, I have a link from them to get you 10% off.
