I can also speak for
Sprocket Data. I also followed the banner from this site about a year ago, and have been very satisfied. They are nice people, and have always addressed issues quickly and competently.
Update: My wife's email address was bounced by Yahoo Groups several times within a year, due to their repeated inability to reach our mailserver. These apparent outages happened several times, and Sprocket never had a answer for it. The second time, I wrote in and never received a reply. Suffice it to say, I have moved on, and it hasn't happened since.
