I own on my different systems...
Corsair 180GB Force GT on my laptop = Awesome
Corsair 120GB Force 3 on my wifes laptop = Very good
Corsair 128GB performance pro on my desktop = UBER AWESOME! Stellar garbage collection and steady performance with compressed and uncompressed data. So much so I just got another in for a raid 0 setup with my new build
Can get them new on ebay for about $145 shipped right now.
Had a corsair 120gb force GT on the desktop originally. Was awesome but overall like my performance pro the best. To note, after firmware revisions early this year, I have not had a single issue with any of my sandforce drives. Just flawless as my marvell based performance pro!
