I voted for the Dragonfly, because it was the first folder I ever bought (besides a SAK) and now - several more folders later - it's still one of my favorites. It's like a mini-Calypso, you can't go wrong with it. Don't worry about the AUS-8 steel, it's plenty good enough for any normal use. Whatever knife you buy, you'll have to sharpen it from time to time anyway, no matter what steel it's made of.
Although, if you do want nice steel in a very compact and reasonably priced folder, take a look at the Fällkniven U2. Yeah, I know, if only it had a pocket clip and a spyder-hole...
