Just think of the bad thing before you blind yourself with the good stuff.

Talk to as many people as you can about your plans and listen to their opinion with a clear mind. If you can't solve the problems they present to you, chances are things are not as promising as it seems.

Do you know the procedure in taking imported goods into Malaysia?
Is the manufacturer realiable?
What happen if a unit if faulty... send back to china and wait for new one?
Does this shop have a viable business?...will it close down in a few months?

Reality is normally much harder to swallow.
