Sounds like you are in the same place I was a month ago.
I wanted ready-made tree straps; I didn't want to use a "thread injector" or tie knots in straps purchased from WW, Harbor Freight, et. al. So I was looking at the straps made by hammock companies and reading bad things about them.
After a bunch of searching here, I ended up ordering seatbelt polyester "simple slings"
I wanted loops in both ends, so I ordered (2) 6'x1" wide seatbelt polyester simple slings with 2" loops on each end for $5.34 each. You can save money by ordering (1) 12' simple sling and cutting it in half if you don't want loops on both ends. These straps are much better and 1/2 the price of the straps any of the hammock companies sell.
