I recently made a hammock with the 1.6 HyperD (planning to make a 2nd one with the 1.0). It comes in at around 7oz and was easy enough- even for someone who had to read the instructions to thread the sewing machine. I spent around $20-$30 for the material and 2 continuous Amsteel loops to use as end loops.
Currently using the tree straps from Hummingbird Hammocks. They weigh 1.5oz for the pair and cost $30. I also just bought their bugnet for $40. It’s supposed to be 8oz. I also ordered the button attachment from them for $12. They’ll replace the continuous loops AND the heavy metal carabiners. I’ll put them on my scale when I get them.
After the ease of hammock-making, I ordered a Silpoly tarp kit for $55 a couple of days ago from RBTR. It should come out to 12oz, maybe a couple more. I’m hoping that this will get me under 30oz for right around your budget.
