Quick Close Cash Offers Possible in PA?

[Dallas Martin]

I was discussing cash offers with a fellow Pennsylvania investor today and he said that even if you make an all cash offer you still would not be able to close quickly because the title search is required and can take up to 30 days.  If that's true then it would slightly diminish the advantages of making cash offers because a good lender would only need a few more days to process a loan.  So two questions: 1) Are title searches required in PA for all real estate transactions (even cash offers)? and 2) How long do title searches take?  30 days seems way too long to me.
