I only use Delta, Moen or Kohler. They are the best, standard and easy to repair, use with tools and do anything with - and they are widely available. If I could only choose one, it would be delta. I get delta always unless Moen or Kohler is on sale, as they often are.
Places like Aquaware, Boffi, and Whitehaus are the high end - but I don't think they are as good as Delta
