I would recommend this 3' tree.  We wanted a table top tree and never had a fiber optic tree before.  It's just the right size, and the lights are beautiful.  Turn the room lights off and you have a light show on your ceiling.  This tree is 23" deep/wide which is perfect.  It is a nice full tree, so I wouldn't get anything less than 23" or it will look scrawny.  I hope it holds up over time.  We'll see next year and if there are any issues with the branches or lights I will make another post.
