Great looking, affordable end tables are hard to find.  I love the following choices currently being recommended to long time design clients for their weekend home.

The one above has a British colonial vibe.

This one is perfect for keeping magazines, books, and papers tidied up and off the floor.  It also is based on British colonial style.

This table is light weight and can be moved around easily and put to use in a variety of spaces.

This is rather art deco or French Moderne.  I love the lines.

I love this end table that I ran across at the San Francisco Design Center.  It has a marquetry top and is surprisingly affordable.

This is a sturdy little table.  Perfect for lamps, drinks, and a few books.  All tables available through Shiree Hanson Segerstrom.  Prices range from $546 to $1400.  Ship times varies.  If in stock, two weeks.
