My music upgrade
I used components from previous systems. Powered by my 30 year old (retired) technics pre-amp/amp (200 W RMS); a beautiful sounding Pioneer tuner ($225?) I purchased used 6 years ago (I didn't need it but it was too pretty - and sounded too wonderful to just sit unused), and a pair of Baby Advent speakers ($40?) I found on craigslist 5 years ago. I used these as outdoor speakers to blast music 150 feet out to Mobile Bays edge. Weather worn but still sound pretty good.
I'll bet you can build a good sounding system for under $100 by shopping pawn shops, goodwills, yard sales.
These items all sit on the shelf by the unused tele. I'd add a picture but they're mostly hidden behind the double closed slides.
