eBay (newegg) has the Samsung 840 Pro Series 128GB SSD for $139.99 with Free Shipping. Sells for at least $20 more most other places.

This means that you'll be paying $0.86/Gigabyte but this is the Pro series with a 5-year warranty.

This is the Perfect Upgrade for a notebook.  Instead of buying a new laptop, consider just upgrading your hard drive to this SSD. We upgraded a Core 2 Duo based Thinkpad and were amazed. No need to spend $500+ on a new machine.

• Original Thinkpad boot time 3 minutes
• Boot time with SSD 30 seconds

This is great for anyone using a laptop or a desktop for typical everyday work or anyone who wants to boot up their Operating System faster on a budget. Includes Samsung Smart Data Migration Software and Samsung SSD Magician software - but adapter kit not included.
