As usual the answer ia eBay. I got mine for around $70 if memory serves a few years ago. That was with a pile of CDs.
Its actually pretty useless in my opinion but it looks nice in my rack and lets me say Ive always got an amiga
running. I could just use it as a CD player but these things are old and I dont want to wear out the laser optics. So it sits, a curiosity with a fluorescent clock.
