I plan on sending my stock AM radio to these guys to be re-built

It costs a bit more ($350) but it remains the same look and gives you full AM/FM with low level inputs for XM or CD etc. I prefer the classic look myself rather than the way the USA models look.
The unit is _supposed_ to compair to a modurn pioneer head unit, with 180w RMS output - but I have not done it myself. Once I do I will let ya'll know how it sounds. They also continue to use the stock controls for on/off, presets, volume, etc. Plus add in special key combinations for fade, tone, etc.
