Thus far, I've only used bivy sacks, which are really great, because they take 1 minute to (un)pack, and are relatively light compared to tents. However, they seem to be good for mostly colder and bug free environments. I took the bivy out twice to go camping in south texas during summer time, and both times, the bugs had me for dinner, and I didn't get very good sleep. So I want to give hammocks a try. They're also very easy to setup, and are more versatile. If there are no trees, you can typically use one like a bivy sack on the ground.

Over the last couple of days, I've been doing some searching, looking only at hammocks with bug nets, and have found the grand trunk skeeter beater pro, and the hennessy explorer hammocks. They're currently my top 2 because they rank highly in these parameters (ranked for most important to least important, but still important)

1. large enough to give me a good night sleep. I'm 6'1
2. lightweight (<3 lbs)
3. cheap (relatively, would really like to spend <$200)
4. includes rainfly (I don't expect to use this very much, but it's still nice to have, would have to purchase a separate rainfly if going with skeeter beater)

I've tried looking at other hammocks, but they're either expensive or heavy. Perhaps there's a couple I'm missing out on. Can the hammock campers suggest other options that are potentially better based upon those 4 things I've listed?
