It's not really an Ipac "clone" seeing as its made by Ultimarc, the same people who make the Ipac.
It's been out for a while now, and has gotten good reviews. I'm not sure why Andy doesn't put it up on his main site, because a lot of people don't know about it. The minipac is the same way, with no link on the main page. It's kind of odd IMO, heh.
