HEADGAP REFURBISHED COMPUTERS:
What makes us different is we not only clean and
thoroughly test each system, we many times replace the
hard drives, optical drives, memory with upgraded
replacements. Operator Headgap Systems purchases good
used Mac systems in quantity. Our professional staff of
refurbishers clean, perform over 50 diagnostic tests

basic system software preinstalled. We update the OS

OR SELL YOUR OLD MAC Remember
we pay wholesale prices. Many times when you are ready to
upgrade your old used Mac system may not be worth much,
especially to a dealer who is used to buying in quantity
at wholesale prices and has the units shipped in bulk
truck freight. Boxing and shipping your old system costs
a few dollars. Here lately we have been having more
trouble locating older systems people are still buying.
We will begin offering trade-ins or to buy outright
certain older systems. The following are on the list:
used PowerMac G4, QuickSilver G4, G3 Desktops, PowerMac
7300, Quadra or Centris 650, 800, 840, and Mac IICI's and
SI's. The units need to be cosmetically in good condition
and working (at least chiming). Trade in value will vary
from the top wholesale price for extra clean, that exceed
stock configurations and down for less that prime units.
We are also purchasing good used Apple Desktop Bus Mouse
