Cosplay: Make or Buy?

I haven't seen a thread that asked this, so I wanted to ask. Do you guys Make or buy your cosplays? If you don't cosplay, which would you choose to do ? If you bought your cosplay, where did you buy it (online store wise or other), how expensive was it? Was it a good deal? I have never bought any of my cosplay. I made every thing from the wig to the shoes. But its a pain when it eats it's way through your convention money ..
