The problems I have run into with the cheap versions of hardware like this is that they tend to fall apart. For example, my last mini-DVI to HDMI adapter performed just fine... until the glue holding the female end in broke loose. I glued it back, and then the plastic started to crack. The guts of it (the electrical bits) looked fine, worked properly, etc. It was the mechanical design that gave me problems. Replaced it with a (ridiculously expensive at $29.99) higher end version and that has lasted me quite some time.
