Recruitment

I just had a recruiter offer me a $1000 to find out the company of a job that a rival recruiter asked me about. I just sent him an e-mail saying that I wasn't going to do that, but gave him the contact details of the rival company. Long term integrity over short term gain, I hope I've made the right decision. What do you reckon? I know better than anyone that recruiters have no loyalty, and thus don't need to be shown any, I think I just objected to the prospect of being bought.
