Still do think that MSE is the best... even if it use more CPU.. I mean I don't think you suppose to be playing around the computer while it's sscanning anyway..
Sigh.. but you know MSE does have a disadvantage, and that is it can't do 2 scans at once.. like you have to wait for the one scan to finish before you can start the other..
And also, you can't pause the scan, it's either stop it from scanning or you just have to wait for it to finish..
