AD- Yes, climbing grade hardware is expensive, BUT IT IS SAFE! For hammock suspension, don't try to use any hardware that you find at the hardware store. And specifically do not use any 'biner marked Not For Climbing. If you do, injury is sure to follow. Now, to minimize the $$, get bold and look into making yourself some whoopie slings. Way less expensive and ultimately easier to use. Also, with whoopies you don't run the risk of degrading your suspension in the garda hitch.
