My first hammock was a Grand Trunk:

I've since moved on to a larger (I'm 6'2"), lighter weight system for camping, but I still use my GT for around the city and going to parks. You're gonna save money over an ENO.

You'll need some sort of suspension system as well, which would at minimum include tree straps that protect the tree trunk. I think the easiest type is to use something like these, which are heavy but that doesn't matter if you aren't hiking/backpacking.

These two together would cost less than ONLY the ENO hammock.
