I'd start with some music from the following:
Terminalhead (Breakin' Rules is quite similar from what I remember... some of their songs have a bit of UK garage/reggae influence)
Hybrid (heavy classical influence, the Moscow Symphony Orchestra has provided strings for lots of their tracks... whenever anybody tells me dance music is crap and not "real" music I let them hear some Hybrid and they shut up)
Junkie XL ("Hit 'Em With The Roster" is a breaks song, but a lot of his stuff is 4x4...)
Crystal Method (really famous act... you probably already know "Busy Child". Vegas is their first and best album)
BT (the Movement In Still Life album especially)
Burufunk (lots of heavy basslines... check out "Welcome To The Real World"
Propellerheads (you know these guys from The Matrix soundtrack)
Dub Pistols (lots of hip-hop influence)
If you want more deeper, slower paced breaks... check out some stuff from Sasha (Involver album), disk 1 of Anthony Pappa's Balance mix, UNKLE...
Oakenfold also has some other breaks tracks... check the soundtrack to Swordfish out, or his original "Bunkka" album (that's where Ready Steady Go is from). You into any of the 4x4 stuff?
