I have it. Let me counsel you to buy only the Blu-Ray version. The standard DVD transfer is absolutely AWFUL.
Here's one review on Amazon: "Rather, what I would like to briefly comment on is the utterly pathetic transfer of this classic film to DVD. It states quite clearly on the back of the cover that this film has been digitally remastered. I took that to mean both video and audio. WRONG. The picture quality of this DVD is shocking, one of the worst I have ever seen. Believe me when I say this -- the VHS version I purchased in 1991 has a better video clarity than this. At times it's actually difficult to make out the actors features. The company behind this, ARTISAN I believe they are called, should be ashamed. I have a copy of the recently released and remastered CASABLANCA DVD. That film was made in 1942, yet it looks as if it was just made, such is the sharpness of the video. The Quiet Man deserved the same treatment, but didn't get it. Shame on ARTISAN."
There are no reviews specific to the Blu-Ray version, but it's $17 and might be worth a try.
Until then, my laserdisc has a better image than my DVD copy.
