I love to backpack, but have never, ever found a good solution for comfortable sleep, so I dread the nights. A hammock setup changed all that. Sleep better out there than at home, in some cases.
The model I have is a Hammock Gear Zippered Bug Net Hammock for $129. Basic and functional. I think with all the clips and slings, etc. it probably set me back $200 in total. Saved money on the underquilt by repurposing an old sleeping bag or using an insulated pad inside the hammock, but that can be an extra couple hundred depending on the brand and quality.
Anyway, great purchase and I'm oh so happy about it.
