Entertainment...

So, our TV is ready to die. It makes this horrible booming sound whenever you turn it on. We're ready to buy a new one, we've chosen the model and store. The big issue is the removal of the old entertainment center, and the need to purchase a new one. Plus, if we're downsizing the furniture, where does all the stuff being stored in it go?

So, what I need from you is thoughts.

Where to buy an entertainment center?
What are good types to get...
Where can I put all of my stuff barring throwing it out? (DVD's, action figures, collectibles, game systems, dvd players, arrrgh)
