I've seen some wide ranges on what a searcher should expect to pay for due diligence on smaller deal sizes ($1M-$5M deal range). Looking for anecdotes where making an investment in 3rd party due diligence paid off for you. I'm of the opinion that, as a prospective buyers, you should be intimately aware of all financial/legal/technology details of the target company and by paying a 3rd party to do this tedious work you are 'cheating' yourself of that knowledge. What am I missing?

Keeping anonymous because I am not ready to broadcast my intent to search.
