I've gotta say I prefer the DIY route. I recently got into this whole hammock thing and half of what I like doing it the DIY creations and seeing them work. The thread injector (AKA witches machine) was tough for me to learn, but after you get the hang of it, the knowledge is invaluable since June of this year I have DIY'ed a hammock, whoopie slings, hex tarp, and under quilt. I've saved a ton of money and really enjoyed it.
My hammock cost under 30
Whoopie slings were maybe 10 bucks
the hex tarp was a bit more but still only around 40
