Crucial offers the factory-refurbished Crucial 128GB M4 Serial ATA 6Gb/s 2.5" Internal SSD, model no. FCCT128M4SSD1, for $29 with free shipping. That's a buck below our February mention and the lowest total price we've seen. (It's also $45 below the best price we could find for a similar SSD elsewhere.) It features read speeds of up to 500MB/s and write speeds of up to 175MB/s. A 1-year Crucial warranty applies.
