What is a good website builder?

There is no "best" web site builder because they all serve different purposes. If you want a basic web page you can simply use Facebook or if you'd like a blog, blogger.com. The tricky part is when you want to run a business online and need the site to have e-commerce functions. In the realm of e-commerce web site builders there are also lots of options but for starters you can try websites-now.net, volusion or shopify. Once you can provide a better description of what you need then the answers will be more accurate.
