I have an Eagles Nest hammock with rain fly, bug net, and tree straps.  I got it off the internet a few years ago for less than $200.  It is very comfortable and everything rolls up into a bag about 16" long by about 8" in diameter.  Weighs about 4 lbs.  It beats a tent.  More comfortable than sleeping on the ground.  Haven't used it in winter.  Cool in summer.  I got the wide one for double occupancy.
