Hi Bro, I had previously install a ceiling Fan-SkyHawk 5 blade 40 inches from Allied Fan Industries in the living room. I feel that the wind is not so strong and intend to change it to KDK brand. My living room is about 15.5 X 13.5 X 8.7 (LXWXH). May I know which KDK model is suitable and what is the price including installation:= - M48SG - M56SR Thanks.
