earphones with mic

I was wondering if anyone could recommend some earphones of the in-ear variety which come with the little microphone attached to the wire.

I currently have ep-630s but I lost the rubber ear bud so I'm taking this opportunity to buy earphones with the mic so I can shout at people when I play online games (particularly Left 4 Dead and CS: S) I don't particulary want to pay much north of £20. I found some ep-630is which look nice but cost 6 times more than its non-microphone brother.

Thanks, Englander.
