well if you want cheap then go with pvc
if you want reliable you need metal, so you can go to a junkyard, get scrap metal, and weld that shit up. if you cant do that it might cost you some $$.
I saw a newborn baby with wild wolves all around it
I saw a highway of diamonds with nobody on it,
I saw a black branch with blood that kept drippin',
I saw a room full of men with their hammers a-bleedin',
I saw a white ladder all covered with water,
I saw ten thousand talkers whose tongues were all broken,
I saw guns and sharp swords in the hands of young children.
