I haven't played them, but before starting a long-term published-adventure campaign a short while ago, the DM and I discussed what was well reviewed and what wasn't.
War of the Burning Sky was very well reviewed, and takes you from 1 to 30. Earlier adventures need updating to MM3 numbers, but that's not much work, and there's tons of stuff on the web that's already been worked on.
Gardmore Abby gets rave reviews, but has only a limited level range.
Zeitgeist is very inspiring (especially if you're not afraid of mixing a little technology into it), but it's not finished yet. Nonetheless, it'll probably publish through to 30th.
King of the Trallhaunt Warrens (WotC) is well reviewed, but it's only a short series.
The Chaos Scar series (WotC) is well reviewed, although in need of some corrections (a few say some maps need fixing). No idea of level range.
