I like Hover.com a lot.
Based on just my multi-year experience with a reliable interface.
So anyone else with a view on the company might chime in. But I am writing this because I have been very happy with them. None of the glitchy inscrutable experiences so many companies manage/love to design into their services.
Oh, the checkbox that turns off automatic renewal can take a second or two to register. So not perfect, but close. If that sounds trivial, you have understood why I like them.
