A few I can think of that have a deep sub-bass and a great deal of distictive originality are:
Subhead - Disturbing House EP
The Susual Suspects on Sativae recordings (the whole double EP) check out Si Begg and Steve Glencross for the killer the subbass.
Tube Jerk - Brainbag (on the B side to Dirty Black Discoteque)

all worth dropping in any mix, imo
