That's a ringing endorsement for the quick release system, but with the disks I linked to, there is no need to swap disks very often. A box of 6 lasted me quite a while. I finally ran through the last of them when I tiled the backsplash in my kitchen, glass and aluminum weren't the best things to use the disks on.
I always wanted a Foredom, but I have always been too cheap. i have a cable driven Dremel remote, but I have never used it. Maybe I'll try it now that the dremel itself is acting up.
