Summary: I plan to buy an entry level class home projector. I've found that it costs $89xx for "Hong goods" with white screen and $79xx for "Water goods" at a store Gxxxx Rxxx in Mongkok. The salesperson it is brand new. Is it that cheap or close to the market price? Would it be second-hand but retuned for sale as brand new? It costs $93xx at well-known chain retail store though! Please anyone can help? Thanks.
