Shadowrun dungeon crawls. Options

[Anymage]

One thing that really drives me up a wall about Shadowrun, especially lately, is the utter dearth of entry-level products. The novice GM is expected to grok metaplot, balance, pay rate, setting, etc. all on his own. Very tricky, and very unpleasant.

I want to get some friends started in Shadowrun soon. However, I am far from the must-own-every-book type (I want to run things with the BBB and only the BBB). I'm absolutely horrible at winging the whole fragging world, though, and want to make them shadowrunners, not fantasy heroes or random citizens of the sixth world.

Out of the published Shadowrun newbie products, only the Quick Start Guide has anything close; First Run has one interesting scene, one piece of metaplot wanking drek, and one overly open-ended and non-shadowrunny plot. The adventures on the main site are even worse, being simple advertisements that have none of the information a novice would need to get into the game at all.

So what I'm looking for are dungeon crawls. Plain, simple, unashamed-of-it dungeon crawls. Primarily site-based runs complete with maps, stats, and basic troubleshooting that have little or nothing to do with metaplot and Shadowrun's constant self-referencing. Slow and basic introductions into the world of shadowrun and what it is to be a shadowrunner, so I can focus on just knowing the site well enough to improvise and not have to completely change tracks when the group wants to go raise hell in the barrens. And with a shallow enough learning curve so that I can have the basics under my belt before throwing shedim-possessed, orichalcum-laced great dragon cyberzombies at them.

So are there any good, basic entry-level products/adventures out there, and if so, where can I find them?
