I have this cable and a £40 one I bought when the Playstation 3 first came out, and I can safely say that the two produce an IDENTICAL image. There's absolutely no difference in quality between this, extremely well priced one, and the over priced ones that the oh-so-convincing sales reps might convince you that you need. Disclaimer: HDMI cables are digital cables, not analogue, and therefore don't differ in quality the way analogue leads used to.
the 1.8M cable in this case is perfectly long enough to come from the back of the television to any Blu-Ray player, PS3, Xbox 360, etc, with a little bit of give as well - and it's not so long that the data transfer commits the image to loose quality (the length DOES make a difference with digital cables - shorter the better). If you have a HDMI port in the back of your monitor, you can also use this for that - I have tried it with both the PS3, and Xbox 360 and it looks fantastic. A perfect cable in all respects.
