Making your own control arms?

[abadsvt]

I was checking on what control arms cost and it blew me away. Just for the control arms is about $700 and up. I have seen alot of different post about people building there own frames and i always see that they build there own control arms. This sounds like a cost effective and kind of fun to do them. Has anyone have personal experience building a set? Is it harder than it seems? I have the money to buys some but it is hard to justify that much money. I know i can always use the stock ones but they are VERY big and bulky. Any comments or possibly a thread on someone building a set would be appreciated very much. Thanks Josh
