QTR-Quadtone RIP

can anyone tell me where i can find QTR ICC profiles that others are 
willing to share?  i would like to experiment with a variety of 
different papers and don't have a spectrophotometer so i'm hoping 
there's a public exchange forum or something where people are willing 
to share their profiles.  i figure a canned one is better than none at 
all.  thanks!
