Check out Pedal-On, I second Brandy on that one. Also look at some new tunes from Zero 7 (mellower techno, good for warmup, cool down, long winding spins) -- something different to try....I found them on iTunes. I also like Cafe del Mar (also on iTunes). They have compilation CDs, I've found some good ones on there CDs.

I have a whole list of artists I could send you, let me know -- sometimes there's artists you just don't come across.
