I use a dd frontline hammock (ddhammocks.com). It will not break the bank, it cost me about 65 euros (say about $90). has a double layer so you can insert a sleeping pad, is strong, has good mosquito netting with zippers on both sides for easy entrance, is VERY WELL built, stitching is great. has a very comfortable lie if you don't pull it tight like dd suggest.
the only drawback, which is a drawback on many hammocks you buy, is the suspension system. There are much better/stronger/lighter/less saggy options for suspensions than the default suspensions used by the companies.
Check out
www.hammockforums.com for loads of good information about hammocks...
or you can just build them yourself, I did too.
here's a picture of one of my homebuilt hammocks, made from parachute ripstop nylone 1.1 oz/sq.yd, with some of my kids in the woods.
you see a suspension of amsteel rope (samsonrope.com), some webbing strapped to the trees with two endloops, and a ridgeline to get a comfortable sag..
I really like hammocks, imo they're much much more comfortable than lying on the ground..
you just gotta know how to use them..
1" webbing and amsteel blue 1/8" cord (whoopie sling)
hammock attachment and ridgeline attachment, the loops you see in both pictures are soft shackles, essentially they are carabiners made of rope (and much lighter)
