So much Bach, where do I start?

I think I could really get into J.S. Bach, but I want to start with music that has characteristics I know I like.
Likes:
up tempo,
percussive/choppy
different voices simultainously playing different melodic lines,
modern recording,
virtuosity (duh)

Dislikes:
harpsicords,
organs (from what little I've heard...no percussive faculty)
quiet music (for the moment)

I've been researching some with Napster and for soloists I like really like Casalas and Segovia, but the recording quality is kind of distracting to me. I also quite like the Double Violin Conerto Viviance (even despite the harpsicord ;) it's the only non-solo music I've found so far) and the piano Fugue stuff.
So, any particular CDs to check out? I need something to compliment my first good stereo system!
