When it comes to doorbells your options are pretty limited. You can go for the old-school "ding dong" or you can spruce it up with whatever is sold in home goods stores like Home Depot or Lowes. Or you can wait and cop the Swann MP3 DJ Doorbell.
As the name implies, the DJ Doorbell will play any song of your choosing when someone rings your bell. All you do is place the receiver outside your crib next to your door, load the SD card with the song you want played, place the speaker wherever you need it to be (as long as its within 165-feet of the receiver), and wait for someone to come to your spot.
There's no word on when the MP3 DJ Doorbell will be available, but when it is, it'll reportedly retail for $50.
