If you do go for DVDFab, and if you do decide to buy it, that 20% discount that runs out in a few days will start over immediately. Get the lifetime rate. You can run it on as many computers as you like, as long as you don't run it on multiples at the same time. IOW, I can rip something on my netbook at work, then come home and use the program on my laptop as long as it's shut down on the netbook. Also, the lifetime gets you free major upgrades, and you can run different major releases at the same time on different computers. I can run v7 on the netbook while also running v8 on another computer and v6 on a third!
