Used PC, laptop and cell phones?

Where in Jeddah can I buy used used electronic, mainly a pc?

expatriates .com

As per my opinion Expatriates.com is best for Jeddah. Other than Internet, you may buy used computers at Khalid bin waleed street. There is a special shop called Al Afzal B2B. They bring used computer from USA and then sell in cheaper prices. Ranging from Pentium I to Pentium IV

al balad souk (sp?) has a TON of shops with used computers also in the building with mcdonalds in it
