Been using a Sharp SD-EX111 (all-in-one CD player/AM-FM tuner/integrated amplifier) paired with Polk RT-15i speakers, since 2004, as a 2ND system.
The Sharp ($500 retail) was $75 on closeout (purchased 5 of them) and the RT-15i's were $13.50 @ a local thrift.
Difficult to beat sound/convenience wise for the price of <$100.
I'm on the 2ND Sharp (One still stored NIB and gave Two of them away as gifts).
