I work in Ampang Park. Now I stays in Kampung Keramat, rented property. Since I am preparing for my marriage soon, and I think Rawang is still the best choice since landed property around is expensive. 

MR2 is good and nice, but it adds additional travel time to my workplace. I tried travel during peak hours from Rawang tol to my office, (needs about 1 hour++). Saujana Rawang will add southern exit, by the time it completed in 2 years time, I believe it will be great place to stay. Jusco, shop lots and badminton court is nearby (BCH). 

I don't know much about difference between gng and guard... I visit the sales office few times, the guard at around just like Puchong Bt13 type. With a rope and 'palang'. Not much. SA told me the Egreta aim for medium class, the security is much better, with card access.
