I agree, but I found out that a coarse measure for the quality of the supply is 
just its weight. Plastic cases are lightweight and bad shielding. _No_ torroids 
are lightweight and do not shield RF. So look for metal cases, many toroids 
and the chance will be better that you will not have EMI problems with your 
switching power supply. 

The last one I kicked into the wastebin was delivered with my network 
camera. (and it had nearly no weight)  I had to replace it with a linear PS to 
enjoy 80m on my K2.
