The Titanic Inquiry Project is about as complete as they come, and it doesn't cost you an arm, a leg, and your first born child. However, there are advantages to having the written copies as well. Like when you can't get near a computer for some reason. You might try going through the PRO, to which a link has been provided above...or you can go to amazon.com. The last time I looked, they were still offering it.
Thanks to Rob Ottmers and friends, the texts on his site are now more accurate than the original transcripts. I alone have found a number of printing errors that Rob has fixed and no doubt many others have helped also. There are a number of instances where it appears that the printer found an error in a line of type. A new line was made and put into the right place but somehow the old, faulty line got put back into the page in any old place, reducing the text to gibberish.
One text that is really bad is the searchable text on the PRO CD. It appears to have been made by scanning and it's full of errors.
Go for Rob's text files and search them with your favourite word processor.
