I've run almost all of the adventures mentioned so far except for Burning Plague. I've found most of them fair.
One of the best in terms of teaching D&D, is probably the 3.0 Orcfest by Fast Forward Games. One of their better products and a good first level adventure all around.
What I do notice missing from these list though, and that's probably beacuse of their infrequency, are adventures that take place in a city. Outside of some material in the various Greyhawk City boxed sets/details, I can only think of Freeport as having anything fairly recent.
