We have a place called EPC (they have an ebay store also), who “leases” computers to comps/corps. When they are “back off” of lease, EPC “resales” the “used” items to the public.

This makes a Great way for someone to “purchase” things at a “lower” price, but still get “good/great” quality products. They have warentee’s and their own service department.

I’m sure if you look around you can find a “reputable” seller.
