Yeah, it's because they had to rewrite the map file cache system, which meant new versions of the maps were required. That's why CE is 170MB download. If they had included the single player maps, it would have been many times bigger.
Anyway, there's a list of most of the good maps (with download links) over here (at the gearbox forums).
My favorites: Cliffhanger, Fissure Falls, Nightcamp_CE, Transfer. I've heard Casualty Gorge is pretty good, too, but I haven't downloaded it yet.
