I know a little bit about it as I was involved in putting together the web site. However I should point out that I have no other ties with the product apart from that - I don't work for them and I'm not on commission or anything like that.
But from the information I was given for the site, and the little bit of research I did myself, it does look to be very comprehensive. I was also given a demo and it looked very well put together, but I'm a newbie when it comes to this sort of product so its features would mean more to you guys than to me.
Afraid I don't know anything about pricing, but it may be worth dropping them a line if you like the look of it.
