Newegg offers the SanDisk 120GB Plus Internal SATA 6Gb/s SSD, model no. SDSSDA-120G-G25, for $54.99 plus 99 cents for shipping. That's $7 below our mention from three weeks ago and the lowest in-stock price we could find by $3. It features read speeds of up to 520MB/s and write speeds of up to 180MB/s.

Don't mind waiting? Amazon has it for $54.99 with free shipping, but it won't ship for one to two months.
