When it first came out I didn't give it a second thought. But when Blu-Ray took over the HD-DVD's really came down in price. To the point where you can pick them up for.... no kidding.... 3 quid!!! And let me tell you, the HD DVD's are as good if not better than Bluray in terms of picture and sound. While some of the older titles aren't as good if the film is relatively old, but they are astounding quality. And the drive is useful for several reasons
1st, it provides more usb ports at the back
2nd it takes the strain off the main video game dvd drive so it lasts longer
3rd you are able to watch some of the most astounding dvds in 1080p quality that rivals blu ray!
I bought this drive for 14.99 BRAND NEW and it is simply the best investment I ever made for my 360. PERIOD
