I have had very little luck getting a recruiter to supply a range. I've had a few, but they are few and far between. I've also had a few that I've gotten to name a range by first naming something comfortably above where I suspect their range is — to which the reply is then to talk me down to that number.

(And, in the cases where I've done this, I've found out the recruiter's range was well below my own BATNA…)
