Well I think some of us can enjoy a radio rebuilt in a practical way. While I appreciate Denny's attention to detail, as long as it works well and looks good after installation, I think most of us would be satisfied. That being said, the AM band does not always provide the greatest listening variety. That is why some shops provide services that convert the radio to a modern AM/FM setup. In addition, an input jack (some call MP3) is often provided so that an MP3 player or satellite radio can feed in through the radio. I don't actually know how the cost of a reproduction radio compares with the conversion of an existing unit. What I will say is that an unrestored radio that is complete, is worth good money, as I understand it.
Here is one of the shops that can rebuild or convert your radio for you.
