Not sure what to tell you. As you've said, its a broad genre. You may both like and dislike things that are categorized as such. Listening is the only real way to find out.

You can search artists there. I generally recommend Kid 606 or Autechre to someone interested in getting started in this type of electronic music. Aphex Twin is almost too well known to even name, though he's worth mentioning and has some great material;
Chosen Lords was a great recent release.
Yeah
u-Ziq is apt as well. Definitely try out
Lunatic Harness!
After you've accustomed yourself to this style, I highly recommend some of Squarepusher's stuff, but be careful. A lot of it is worth disposing of almost immediately.
Music is Rotted One Note is highly recommended; a wonderful blend of electronic/jazz fusion.
And for the lighter side of things, ambient music is your friend. And even if you don't get along with it very well, The Orb's
Adventures Beyond the Ultraworld is too amazing to not listen to. Anyone will tell you this is so!
Happy hunting. Feel free to ask more, or PM me.
