i don't know of any dealers in america, but try them direct @
www.basscentre.com
they have a link to a site about elite strings,
before i traded in my jazz, thats all i was using, stainless steel stadium series, some people like them, and other hate them, but its like everything
they have a nice sound new, not too sterile, and they age well, last a long time and feel good.
if you can't get them from the bass centre themselves, try
www.stringsdirect.co.uk
thats where i got my elites from, very cheaply
