For Sata III, Might look at the Plextor 128 Gig ($230 after $20MIR)
For Sata II any of the SF12xx controller based (ie vertex -II, I have the Pheonix Pro)
take Sequencial read/write with a grain of salt, it is the least important parameter for a Boot/program drive. Much more important for a data drive working with large files. Try to find benchmarks that mimic real world perfomance (Such as PCMark vantage), then decide if cost/performance is worth it.

And
Quote: As a point of comparison, a file operation completes 85% faster on a low-end SSD than it does on a high-end hard drive, but there is only an 88% speed difference between a high-end hard drive and a high-end SSD. End quote

Only applies to Sata III - Go to new egg and look at reviews (Only the ones with 40 or more responsies). compare Vertex-3/Agility/3/solid 3 (which uses the the SF22xx controller to the Marvel Based controller (C300, M4, Intel 510, and Plextor) - Highly recommend the marvel based SSD, you only losses about 10 to 15 % in real life which most people would not notice.
