Is the RM1100 for inverter/non-inverter?
Is it plasma/non-plasma?
Included installation?
Which chain store u went to?
Which area u live? Perhaps LYN forumer here can suggest stores that sell cheaper aircond near your location.

I suggest you to survey price in 2-3 shops before commit in the purchase.
Fyi, I bought 1.0HP mitsubishi (MSFG10VC) , non-inverter, with plasma, without installation - RM1100.

My friend got RM900 + RM180 installation, in kepong.

I think I get cheaper in PJ.
hmm...if u live near pj, u may want to check out jintex like suggested above and also Happy SS2 and D'Legend, which both the latter are at the same row with Murni restaurant.
