Amazon offers the Western Digital 2TB WD Green Serial ATA 6Gb/s 3.5" Internal Hard Drive, model no. WD20EZRX, for $69.99 with free shipping. That's tied with our mention from last fall as the lowest total price we've seen. (It's a current low by $10.) This drive purportedly consumes up to 40% less energy than standard mechanical drives. It features a 64MB cache.
