It's not easy to do that here cause where I stay you don't get these monitors in every store so I have to buy online.

Online stores must have a return policy, and here online law is the same as retail law.

just need more people to confirm that 120HZ is really better from the day 1 of use.

You can read LightBoost testimonials, as well as the Amazon Customer Reviews of the ASUS VG248QE, for a great sampling of various 120Hz testimonials. It's in your favour to make sure that the 120Hz monitor that you get, includes LightBoost -- see the 120Hz Monitor List. There is now an easy utility that allows you to easily turn on/off LightBoost via a hotkey, called ToastyX Strobelight. This list will hopefully help you to find the appropriate 120Hz monitor available locallly in your country. I should point out that the S27A950D is a nice 120Hz monitor, though it has more input lag than the LightBoost models.
