KXEN, SAS Social Network, Detica Netreveal ?

Hello,

I'm evaluating solutions for social network analysis and exploration. Unfortunately, I can't find price information for KXEN, SAS Social Network or Detica Netreveal.

As anyone used this software and can provide a rough estimate of prices for any of these? I know it depends on many things, but still, just to get an idea would be nice.


Thanks in advance!
