Welcome to the forums. If you have any sewing skills it is quite easy to make your own hammock from a few yards of material. See the info on JustJeff's site.
Lots of choices is you are buying. If you don't need a bug net then you can pick up a hammock for pretty cheap. there are lots of opinions on which to get. ENO makes nice hammocks for cheap. The Warbonnet traveler is a good choice. Many more!
I've always made the decisions easy by limiting myself to what I can make. good luck.
