Do you have a source for wall warts you're selling that you wouldn't

search digikey for "cui 6w wall transformer DC switching ~9.6w"
there are multi-plug ones (various countries, 90-260V) that start with EMS
and US/canada/japan/etc ones that start with EPS
they're all center positive, and come in various plug configs.
theres also, of course, other wattages, but 6 is the smallest
these ones are switching. the linear ones are boxier as they contain a transformer.
ironically, ordering direct from CUI doesnt seem to be significantly less expensive than ordering from digikey, especially with multi-week leadtimes
linear wall warts are definitely cheaper (http://www.goldmine-elec-products.com/p ... ber=G16254) than switching so im not sure what you're referring to when you say 'cheapy'
