I'm not big into trance or techno.
But, I do like house and trip-hop.
Try out some Mark Farina. He has 2 distinct styles, house and mushroom jazz.
Also, I really like St Germain, very jazzy uptempo house (and he is on Blue Note Record label).
For some killer bass, try DJ Krush!
I also like LTJ Bukem, either the Earth (house) series or the progression session series (kind of housy triphop).
For a more Drum and Base/Hip hop sound, I like Ming and FS.
For something a little more on the fringe/experimental, I like Prefuse73, Squarepusher, Autechre.
