Second hand mobile phones (Taipei)

im looking for a market place that sells mobile phones, similar to guang hua shopping centre for computers. im looking for a samsun i8510. it has a symbian operating system, and 8 megapixel camera. i would like to get a phone with 8 megapixel camera and with either windows or symbian o/s. cheers.

Longshan Temple night market (Huaxi St) is the place to go.
Don’t ask me about quality though, as I’ve never bought a phone there.
