'nother Mainer! Excellent.
For my two cents, I'd say either the Hennessy Safari or the Warbonnet Blackbird 1.7 double layer. Both are easy to set up and provide good room, other feature differences aside. However, depending on whether or not your spending lots of time in a Jungle/Rainforest area, I'd go with the Hennessy for that. The bottom entry will definitely 'help' keep critters out as you enter/exit the hammock.
