Thanks for the responses. I thought you'd have some fun with it.
Some responses:
1. No, she does not want multiple speakers in multiple rooms. That would be ridiculous. She just wants it to be loud enough to listen throughout her apartment. Computer won't do that.
2. She doesn't want to wear headphones around her apartment all the time. Just wants background music, I think. Good try, though.
3. The Kloss table radio option is awesome. That is something I wouldn't have considered. The Teac is also interesting. I'll pass those along.
4. Boombox *is* the obvious answer, but it seems to be a cop-out to me. I like the challenge of beating that for $100, especially when they don't sound at all good under $150, imo.
5. The partsexpress option is something to think about, thanks.
Yes, it is an insane budget, but I am not convinced it can't be done well. Just need to get a little lucky, I think.
I am leaning towards the challenge of trying to locate a working vintage receiver and a pair of speakers while garage sale-ing for LPs this summer. That and a Radio Shack connector and we're done. That has to kill a boombox, doesn't it?
Enjoy!
