Good .pdf-format adventures for 4E for around 3-5th starting level?

[Eurhetemec]

I thought I knew what I was going to be running in a couple of days, but the adventure I'd read such positive reviews of simply isn't available, so that's right out. Can anyone suggest good downloadable adventures for 4E, for characters around 3-5th level (a party of 4 4th level characters, I can customize monster numbers as necessary)? There seems to be something of a paucity of reviews of adventures, compared to the number of them out there, both here and at ENworld. I'm not looking for anything in particularly beyond fun and reasonably easy to insert into a campaign.

Dungeon 158 has 'Tariff of Relkingham' - 3rd level, a strong mix of investigation and action.

Dungeon 155 has 'Heathen' - 5th level, action-focused but with a strong gloomy tone.

A month's subscription to D&D Insider will get you both of those for $7.95, plus a pile more (of variable quality) to use later in the campaign.
