I'm voting for the Creative ep-630. Does it sound as good as a KSC-75? Not quite, but it's a passable, comfortable IEM available for way under $30, and it doesn't sound bad at all. Plus I didn't want to be like everyone else and say KSC-75.
disclosure: without realizing it, I wrote this on a public terminal while wearing the kosses, with the creatives sitting right in front of me. BUT, 95 percent of the time, other people would be sitting here too, and I couldn't use these damn KSC-75 at all. Nor could I fit them up my nostrils.
