"NEED" is a very difficult concept to define and, is not, I believe, the main point to deal with here.

The points made in this thread are all excellent, but some things need to added for consideration.

From a man card perspective, an HT room is a must.

Then there is the smell of testosterone in the air as your sub erupts and kicks you in the chest.

And perhaps the most important piece of all. Inviting your friends over for a poker game or to watch a movie, knowing that they are ALL thinking - "He has one and I DON'T"

Oh yes - "NEED" is far down the list here!!!
