I really like the LaCosta and the Cob, those are my choice of the ones listed here. But I like the fact that these can be moved, so if or when you wanted to you could.

Although I do have to say that the post stating that you can also build your own would be a good idea as well. If you were to build one you most likely would not be able to move it, so you would have to make sure that it is in the right place where you always want it.
