well my budget is as low as possible, definitely not more than the price of that ridge rest. I'm not worried about bulk so much as weight as I'm planning to put it under the blanket in my czech bedroll for now. Because it's going to go in there it won't be too accessible so the less preparation needed for sleep the better. A self-inflating mat would probably be OK but the ones available for these sorts of low prices seem to be very heavy. I've definitely thought about a hammock and I might get one eventually just for the different experience but for now I think I'd prefer the bedroll/tarp setup.
