Now, this is not a quesion about the Ellusionist new videos

The videos on said website do look really nice. 25 quid for 16 effects with a new gimmick does sound tempting, but I know I'll be replacing the loops often and it will get rather expensive.
I havn't looked into how much new loops cost though. But anyway, enough with my decisions and back to the question...
Do you guys ever use loops?
