Instead of stealing, which works, but you can go to a local construction business and the dont use the pvcs once they cut of the ends, which is perfect, because they just put them in a huge pile and just sit there. it works best of you know someone that works there, but if not, just go and ask if you can have
(your practicaly doing them a favor) one or more of there old or even craked pvcs. they most likely will say yes since they have no use for them. if they dont, u can offer 20$ or whatever, but its better then 200$. this works for me, hope it helps you out!!
