oh, duh!! dont know what i was thinking..
for a business i usually expect something like aetech.com etc... since i saw superskimmer.com i figured it was a generic skimmer resale site
i had only read the skimemr info page, and hadnt browsed the site itself.
they do state at the bottom that the info listed is generic to all skimmers.
any experts here that can verify that info, and rules of thumb listed? like how much skimming for what application etc...
