You need to build yourself a sellers network, people who will sell you their used/broken machines. These guys owns repair shops and resells broken machines bought from their customers or manage equipments liquidation for corporations. Ebay is a great place to meet these sellers. You have to contact them and deal with them outside of ebay. They will be glad to avoid paying ebay fees and sell directly to you. Look for sellers who list many broken machines and parts, contact them privately and try to establish a business relation with them.
