bkt utama 1 is great. i live there and literally everyone i meet that lives in the condo love it, and all the expats say they couldn't believe how good value it was compared to mont kiara. only 5-10 mins away from mont kiara via penchala link but rent and sale price less than half of mont kiara.
it's very very convenient. right next to 1 utama, curve, centrepoint, as well as ldp, sprint, penchala link. also golf course right next door. management is doing amazing job of looking after place including great landscaping so place feels really very exclusive, and it's very very secure (they have about 40 guards and they often do a drill at the front which looks very impressive!).
really, every single person i know that lives here say they love it. and i love it!
disadvantages:
1) all units are same size except penthouses, so if u don't like the standard 2,000sq.ft layout, it's tough luck.
2) not too much of a mix of races. i'd say 90% chinese, 5% western expats, 5% other.
3) nothing is walking distance (although a LOT of shops within 3 mins drive)
So if that is anything to judge by, bkt utama 2 is worth going for! a superb alternative to mont kiara - oh, and btw the expats are slowly figuring this out and are moving there...
