Hammocks

Hello, I just joined, I don't know how active this community still is, but I'll give it a shot. I am going to Costa Rica with my Girl Scout troop in June for two weeks. We've already set our itinerary (we're going with Rustic Pathways) but do you guys suggest buying the Costa Rican hammocks, I'd love to bring a small to medium sized one home for my room. What other things do you recommend us buying besides coffee?

Also are there places on line to look at hammocks?

Thanks in advance
