What are the best brands for grandfather clocks?

I own two Howard Miller clocks currently, but have owned other brands before. I love the support that HM gives its customers. If you run into problems, they have a thorough website with troubleshooting information. But, if you want to talk to a real person to walk you through a problem, just call them and a live, breathing person will return your call. They also have a huge variety of clocks, movements, designs, wood finishes and features. Their warranty is wonderful, their clocks are easy to operate and require little maintenance.
