Ear Buds? Any good recommendations under $100?

I'm currently using Klipsch S4 buds. I got them new for a steal at $40, but I think they're normally $80 or so. They sounds pretty good for the money although I haven't auditioned any other makes in that price range.

I'm using the shure E3c. I think they were like 200 for the pair, but I got them at guitar center for $60.

Sennheiser cx 300-IIs are still a great buy. Mine are a few years old (the originals) and still sound great, for the money. You can get them for around $30.
