dude, making rails is so much better. For $100 dollars, i am making two 10' flat rails with wood and PVC. its much cheaper, kinda fun, and you can build more stuff as you want. For that much money, you could pretty much go to a metal shop and get them to build you one completely custom. another thing about buying rails is that shipping will be sooooo much money. build yo self some jibs, save some cash, and spend it on hookers.
