My girlfriend's factory in-dash player recently bit the dust. Sadly, she doesn't seem to have the desire to blow big dollars on an empeg, but could well be talked into, at the least, getting one of the MP3-CD players. I see a new crop of them is now on the market, most notably the Jensen MP3510, which Crutchfield lists at $229. Anybody played with these newer machines? Are they worth paying nearly 2x the cost of otherwise generic single CD players (such as the Aiwa CDC-Z117, listed at $119.95 on Crutchfield)?
