Seagate 1TB 7200RPM 32MB Internal Drive for $74.99 shipped after the $15 rebate. Here is a screenshot for your reference. Note that it is in OEM packaging, which means no pretty retail box and marketing materials. This is the newer 7200.12 model, which has been revised to utilize a 500GB/platter design, the highest density currently available for reduced power consumption and better performance. Most places have it for about $90.
