I realize the original poster has resolved his issue, but I'm posting this just as a reference for others.
My lovely wife has cracked her screen to the point it needed to be replaced twice in the last year. First time I paid $100 (including parts) to have a local place do it. The person did a poor job, claimed it was a difficult repair, and the sensitivity was wrong. When she cracked it a second time I fixed it myself using a screen from http://www.directfix.com/
and used this
youtube video. I found it fairly easy and replaced it in about an hour taking my time. After my repair, it works fine although I did have to clean out some dust once (not as well sealed as factory obviously). I believe the screen, plastic pry tool, and small screw drivers was around $64 including tax & shipping. I have no connection to the company that I purchased the screen and tools from(just stumbled on them via google), but I am happy with their service.
I am an engineer and do have a little experience taking apart other electronics, but I am by no means particularly good at it. It's definitely doable by anyone with the patience, and I had no trouble replacing just the screen and not the LCD. It may have been a bit easier for me as it was the second time the phone was taken apart.
I've made Gorilla Glass a requirement for my wife's next phone...
