Ok, I will have to check the DIY out!
Sidenote, is the HH supershelter pretty much a WBBB double layer with a pad in the middle? If this is the case, it would make a better price argument to get the WBBB and a nice pad to put in the middle. If not, then it looks like its pretty hard to beat the current HH SS special right now.
Im just finding it hard to get something close to the price of the HH SS kit and still be a complete mild weather setup.
