Rusty Blade/a.k.a. Craggy Lotus can often be found on the Ukjuggalos.com forum, and Foogz is sometimes on there too.
UkJuggalos itself is a great site, so if you've never been there, check it out biatch.
There's also of course the official Psychopathic Records websites:
europathic.com
insaneclownposse.com
and more.
Check out play.com for cheap CDs
and anywhere else you wanna go.
