My last one was Experian. Online failed and had to go the paper route. It came in 6 calendar days.
Trans Union online has always worked for me, but Equifax is failed to provide the online thing the most.
I have the paper form in electronic format, already filled-out, along with scans of the appropriate documents. So if any of them don't cooperate in the online process, I just print that and mail it.
