Please bear with me because admittedly I am a noob, but I am loving my new Phantom 3 4K. In order to take care of it I'm in the market for a backpack to place it in general, and the occasional travel. As I don't want to spend all my money on the bag (I would prefer to spend it on memory cards and spare batteries) has anyone had experience with a backpack similar to this?

I know it's fairly large, and I would prefer something similar to the hardshell that I see around since it's lighter, but I can't seem to find a cheap version anywhere.
