A bunch. I had one controller, but it was one of those crappy controls(I remember you could change the face-plate), and whenever I pressed A, it would register twice, but my brothers thought it was me. Then I may have gotten a controller, not sure, but I finally got my own gamecube controller. My brother eventually broke his, so I let him use mine after I got a neat little Micro Controller, which worked suprisingly well. I eventually broke it though, then I got another. Sometime later I broke that one, then I got another...and after breaking that one, I had to use the wii-mote until I finally got my replacement, which was a platinum gamecube controller and since then I haven't had any problems with controller except for the fact that the one my brother is using has a screwed up c-stick.
(Oh, and this happened over a period of a few years, from the begining of Melee to Brawl. So no, I don't have really bad anger problems-but that still hasn't stopped me from throwing my controllers before.)
