Cheap Second Hand PC

Just got home to Taiping, and mum said that in
Singapore, second hand PC can get with less than
S$100. Wow... can we really, I asked her to go ahead
and order it... It seams got some contact la... some
relative in Singapore spoke of it... we will see how.
Maybe I can mail my cousin in Singapore and ask... I
will be passing by Singapore in a couple of weeks
time, if really got so cheap, can get one.. hehe..
wonder how much is a second hand mac...
