There is a review or 2 here you can search for that goes over the SG bags. It may give you some info to help you understand the features of the bags and you can decide if its worth the money to you. As with most things you get small improvements as the price goes up.If you don't mind me asking. I have a nemo backpacking sleeping bag that is ridiculously lightweight and comfortable and got it for $200. Why are those hunting brand sleeping bags so damn expensive?
