I'd love to see proof of this claim. The FBI covers the cost up to about 30 pages. Even the sample letter [0] the FBI gives you to use includes the following:
I am willing to pay up to [$____ ] for the processing of this request. Please inform me if the estimated fees will exceed this limit before processing my request.
Mine were from DARPA. The docs I was requesting should have been rather large (~100 pages x 15), so I was willing to pay up to $500 for 'em. Instead, they sent a curt reply (1 page or so) and a bill for $80. I'm not willing to post 'em publicly... but my email is in my profile.
