To get back to the original subject.
I would forget about the computer element. The Winradio is superb and highly thought of but it is also highly priced and you will also have to set up some sort of antenna.
Look on eBay under Radio/Scanners and you will find loads. The Yupiteru MVT7100 has a good reputation & good frequency coverage that will let you listen elsewhere when you want to. The Alinco DJ-X3 is also quite good. There's loads that might suit you.
