profile prism???

anyone here create a profile for their printer?? has anyone used a system called profile prism?? http://www.ddisoftware.com/prism/about.htm I am wondering if anyone has any experience with this program.

I bought it about 6 years ago when I had an Epson 2200. For what it is, it works very well, you have to have a pretty good scanner for it to render the test pattern correctly. I haven't used mine since I replaced the Epson about 3 years ago.
