The Kingston V100 series are still great drives and they're very reliable. The V+ 100 series are also something to look into if you're looking at RAID 0 configuration as well. As you know TRIM will be disabled when you set RAID to SSDs, but the V+ 100 will perform efficiently even in RAID because of its individual built in house cleaning function. For a single drive, the V100 will be a great upgrade.
There's really nothing to worry about the new Sandforce drives. Corsair and Mushkin has great support and firmware updates will fix most problems.
