Source Book Reccomendations, What source books have inspired/amused/aroused you? Options

[SIN]

Hello all,

I've been playing Shadowrun, somewhat sporadically, since 3rd ed., but have never really played seriously or consistently enough to warrant buying many source books. Now that I'm planning on running a campaign for a few friends, and now that Cambridge (UK) has finally gotten a game store again, I'm thinking that it might be worth picking up a few fluff books for ideas and inspiration. I'm setting my campaign in a home-brewed version of the UK (with a definite V for Vendetta/1984 flavour), and I'm pretty pleased with my timeline and general ideas thus far, but there's definitely room to flesh out my vision by borrowing (blatantly stealing) good ideas from source material. I'd be interested to know what source books people have read in the past that really inspired them and the way they ran their games? Did any particular book inspire a really memorable run/character/NPC?

Please bear in mind, my current knowledge of the sixth world doesn't go much further than the history based stuff at the beginning of the 3rd and 4th ed. rulebooks, so any source book would need to be pretty self-contained. Also, whilst I'd still be interested to hear about the older source books, please bear in mind I'll probably struggle to get hold of anything pre 3rd ed.

Finally, a few specific questions:

1) As I'm setting my game in the UK (albeit a completely non-canon version) I'm considering picking up Shadows of Europe (it's in the game store and only 3rd ed. I believe so not too far behind the current timeline) - what did people think of this book?

2) What's are people's opinions of Runner Havens and Corporate Enclaves? I'm struggling a little with my image of London in 2070 overall, though I have a lot of ideas, so a book with good sprawl descriptions and interesting well fleshed out geography would be helpful.

Thanks in advance. I know you guys'll come through - I've never had to start a topic before, because the answers to all of my questions have always been hidden away in here somewhere!
