【答案解析】[听力原文]
M: Good morning, I'm looking for a new stereo for my living room.
W: Sure, I'd be glad to assist you with that. This model here is a brand new one. It has a DVD player, AM/FM tuner, and a connection for an MP3 player.
M: It looks nice, but it's a bit out of my price range. I was hoping to find something cheaper. Do you have anything that is less expensive?
W: We sure do. The HS100 is the same brand, just the older model, it has similar options, but it's less expensive because it has been discontinued. I will show you our catalog.
