All depends how lightweight you want to get, right? So, if you want a legit backpacking setup, suspension is in the $30-40 range. I like Arrowhead Equipment as a cottage guy. Here's their kit. They have an option for a ridge line, which I would suggest.

Hammock are going to vary wildly in cost. You can go for filthy cheap from amazon, or opt from one of the many vendors out there for a higher quality one with better dimensions. If you're handy with a sewing machine, or even barely literate with it, you can make one pretty easily.

That said, I might edge toward pushing a little over my estimate here. You could go with Arrowhead here as well for $45-50, depending on your height.

Or a great medium price, everything-included option from dream hammocks like this.

Or dead filthy cheap like this, preferably if you're under 5'6", but I used a similar one for a while before I moved onto my DIY setup. Use the arrowhead length guide to give you a general idea of correct length.

Like all things gear, this is a serious rabbit hole.
