Where is a good place to get REALLY cheap computers or laptops?

Laptops and computer hardware are well priced at Newegg.com

I don't know any American companies that do full desktop systems.

Local newspapers, Ebay. Cashconverters, are three examples where cheap laptops may be found. Also shops selling computers and laptops sometimes have a low cost machine on offer - maybe a last of the line, or display model.. Look out for refurbished machines. Maybe a family member or a friend may have one you can have or buy?
