Shel, I used InfoSpace for a short while. I have not tried it lately, and I may not give it its deserved due since I have not. I have read lots of users here who like it.

Beyond411 was developed free by a user here who has continued to update and support it here on these boards., and responds well to questions and update/feature add-ons from users here. It is a great great application, just for someone to throw to me free, so for that reason, I personally prefer it.
