I have one of their cd's that I picked up last year in a used shop. It's ok, but sounds a little dated. Honestly, if I had bought it new "back in the day", I probably would have loved it.
EDIT: I have The B*tch Is Back. I had to look it up because I couldn't remember the name of it, so that should tell you something. I'll take Girlschool over these guys and gal.
