DUE DILIGENCE CHECKLIST FOR SEARCHERS
I've seen a couple of people posting in here asking for Due Diligence Checklists. I came across this one which is pretty good. Just enter your email and it's free!

In addition to hinting at the size of the DD request, I would add the following information for each requested item:
(1) It's priority level (in case some information is not critical)
(2) The (negotiable) date by which you would like to receive it
This helps keep the parties on the same page and hopefully prevents the process of due diligence from damaging the deal.
