Just get a used one in a thrift store, about 10 to $20.
I pay $15 for my high grade Kenwood receiver with an excellent tuner section, and it is 50 watts per channel.
Used stereo receivers are very cheap now, and they are eveywhere.
And it is much too nice (my Kenwood) for my computer or casual listening.
For my computer, I can found something for about 5 to $10, with 30 watts per channel stereo integrated amp (don't need a tuner here), and it will do the job very nicely. Check places like Audiogon on the internet... And thrift stores or second hand stores... Salvation Army...
