We've all seen examples where one clamp-on bead can work, but I don't 
think that negates Tom's point.

If one bead is enough to solve an RFI problem, it only proves that the 
problem was a "soft target".

The majority of problems are tougher than that, and need stronger 
solutions - which all involve more effort than a single clamp-on bead. 
Unfortunately they also involve activities like cutting cables, removing 
plugs (to wind toroids) and using a soldering iron... all of which are 
fine in our own homes, but not so good in other people's.
