I've got LOADS of it. Although there are many different types of DnB, it's kinda hard to say where to start. For example, you've got Liquid Funk, which is my favorite, which is the more uptempo, happier kind of DnB, and you've got stuff like Dieselboy (not sure exactly the name of the genre, but it's very dark and heavy, sort of like the heavy metal of DnB).
I would highly recommend Hospital Records to start. I've been folowing them for a few years now, and have a huge collection of their stuff. My favorite artists on Hospital right now are Cyantific, Danny Byrd and Mistabishi. Hospital also does a bi-weekly podcast where you can hear all kinds of DnB and find new artists. On the other hand, I would recommend Dieselboy's Substance D album, which is very dark and heavy.
Of course there's plenty of other DnB out there. I'd check out Dogs on Acid which specializes in DnB, if you want find some stuff. Enjoy!
