Amazon offers the Patriot Pyro 120GB 2.5" Serial ATA 6Gb/s Internal SSD Solid State Disk, model no. PP120GS25SSDR, for $159.99. This $40 mail-in rebate drops it to $119.99. (Fry's Electronics charges the same, with in-store pickup only.) With free shipping, that's $1/GB and the lowest total price we could find by $71, although we saw it for $3 less two weeks ago (since expired). Rebate ends February 29.

Note that Amazon lists it as temporarily out of stock; it's still available to order at this price.
