Best place to buy LCD TV

Can anyone give some advice on the best place to buy good price and quality HD LCD TV (40 inch)? I know they are widely available but keen to know if there are some places that sell for a lot cheaper? How about Shenzhen?

thanks very much!

Regarding used LCD TV s .... now ,in HK , second hand market for used LCD TVs is a risk unless you buy from a store who firstly has been established for many years in the same premises and secondly , the dealer must be knowledgeable ,open and honest . You can find this on the first floor of ChungKing Mansion . Kumar Electronics who has been operating repair and sales centre for more than 20 years . Top brands , Japanese , European , Korean , Taiwan and China . Lay bye , buy & sell or trade LCD TV of all sizes . Wall mounts and remotes available . Kumar is a Master technician and repairs ALL electrical & electronic appliances , even digital & video cameras . blenders , microwave ovens , but especially TVs . Honest and reliable plus excellent fair value .
