I once bought a Chinese radio controlled wireless shutter release for my 5D MK II. That was junk. Then, I bought two Benro heavy duty CF tripods at $400 ea and two Benro heads. The heads were junk, the tripods were fine, but last winter I went to get some replacement parts from the US distributor, and found that they could not supply them or get them, and that parts had never been available. I also had four Sigma EOS compatible lenses, but, when I went to use them on my Canon DSLR, they would not work. It turns out that Sigma had reverse engineered the lenses poorly. Only one of the four could be rechipped, and they charged me $100.
It generally costs less in the long run to get good quality. That does not always mean buying the most expensive, but it does mean paying attention. I no longer buy Sigma or Benro, I've been burned to too many Hundreds of dollars.
I did buy some 3rd party batteries one time for my original Canon Digital Rebel. They lasted two or three months.
