I know you didn't want to see any of those canalphones, but the Creative EP-630's are really nice. I often fall asleep while wearing them and they don't hurt even if you're on the side of your head. They're also excellent at blocking outside noise. I used them at a party last weekend because the music was bad and I couldn't hear a damn thing! It was great.
They go for between $20-$30, but you can also get them off eBay (where I got mine) for <$5 (got mine for $3) and they're the real deal plus they come with 2 additional ear bud sizes.
As with the Pathfinder's I've owned a pair of those in the past and didn't really enjoy them. I had problems with them staying in my ear and the foam disconnecting from the plastic casing. Ended up returning them a few days later. Of course these could be an improved version of what I had can't really tell. They look the same, but I had mine back in 2007.
