The agent will pull you if you start ******* them around, especially if he's got an exclusive arrangement. He'll just tell client co that you've withdrawn your interest.

It's just not realistic to quote a binding price before the interview. We've all been to interviews where the details don't match what was in the "spec" the agency provided (whosever fault that was). Quoting a range before the interview and doing the rate negotiation immediately after the client says yes has always worked well for me.
