Update 2,
I met 2 suppliers today and both told me that one side of our walls are too thin to install the DC Moto properly. Refer to the attached picture. As you can see from the attached picture, the mounting plate it too thick for our wall. Hence it was suggested to us to fabricated metal pillar (filled with cement) so that it can be installed.
For our group buy price:
1. Mr.Autogate - GFM925W - RM1350 (1 year warranty)
2. Jason (recommended by LYN) - GFM925W - RM1500 & GFM925AL - RM1700 (2 years warranty)

The difference between GFM925W and GFM925AL is that the AL version cannot be forced open as the lock is located on both side of the gate instead of only at the actuator.
When I had a chat with both of them, I am more inclined to Jason as he seems to know what he was talking. For the idea of fabricating the metal pillar, it was actually his idea.
Oh btw, the prices are not inclusive of cabling between your DB and gate. Plus, Jason recommended that the autogate to be the last installation as there's a tendency of acid cleaning prior to moving into your house and this acid fumes would damage the autogate arms.
