Boombox that has compact flash

I don't know what your budget is, but I use a Tivoli PAL which has an Aux
In socket, and feed in the headphone input from a NexII.

The PAL is a standalone portable AM/FM radio with excellent reception and
a beautiful sound (IMHO). It has a rechargeable battery that lasts for ~20
hrs. The downside is that it cost ??130 or $130 depending where your based,
and its mono. Given that boomboxes have poor physical speaker seperatiom,
I don't see that as much of a problem.

The NexII costs ??60/$70 or so and takes any size CF you can find.

The two combined would be smaller than most boomboxes.
