I bought my Aircon at Best Tech IMM. Keith Chua, the salesperson there was very helpful and informative. They have a lowest price guarantee until the date of installation. WOW. I bought Toshiba Inverter System 4 with 3 X RAS-M10NKCV with 9000BTU/hr & 1 X RAS-M22NKCV with 22,000BTU, the compressor 9outdoor unit) is made in japan 1 X RAS-4M30ACV for $3440 inclusive of GST. The Mistubishi Starmex one is about $50 odd dollars less. Went to other shops not so helpful and detailed. Best Tech has a special cover for the copper? piping and many gifts/ service vouchers and others. Definitely check out this place esp. keith. you'll never regret. I am thinking of engaging City Designs at IMM for my ID any remarks. another option is Decormark. Pls email me. threbto@yahoo.com thanks
