I just picked up a hammock from Legit Camping and I'm thoroughly pleased with it. It's a little higher in price than some of the others, BUT you do get a lifetime warranty on the hammock as long as you register within 30 days of purchase by following a simple link, and they still aren't as expensive as ENO.

Also, the co-founder of the company personally followed up on the purchase and made sure I knew about the time limit and that I had to register for the warranty. Seems like a great company and they make great hammocks if you want to pay just a few bucks more than the cheapo hammocks.
