Amazon offers the SanDisk 128GB 2.5" Serial ATA 6Gb/s Internal SSD, model no. SDSSDP-128G-G25, for $64.99 with free shipping. That's tied with last week's mention as the best no-rebate deal we've seen. (It's a current price low by $12.) It features read speeds of up to 490MB/s and write speeds of up to 350MB/s.
Expect this item to take up to 3 weeks to arrive.
