Query: A stellar performer in its time, but now a bit behind the curve

I just replaced one of these units (Toshiba SD-5109) with a brand-new Oppo 980H, and while the Oppo is leagues ahead of the old Toshiba, the SD-5109 has served me well and given me no problems. I'll hold onto it for a while because I couldn't get much for it today, and it may come in handy sometime. (I can always use it as a CD player in one of my many "B" systems scattered around the house.) If you happen to run into a working SD-5109 at a flea market or thrift store, you could do worse than buying it for $25.
