I went ahead and signed up. I really disliked having to put credit card and personal info into their site but I did it anyway.
When I pulled up the first item, a window opened which said it was my 4th lookup. Since I am supposed to get 5 free ones during my trial period, I took the info which was not all that useful as it turned out, and then cancelled out. Getting out was not a gut cinch but I made it even with my limited skills.
All-in-all, not worth the trouble to me and I would hate to think I had to pay them a fee for the service.
