Decent receiver w/an alarm function?

OK, this question is out there... Right now in my bedroom I have a little Nakamichi system--basically a glorified radio alarm clock. Basic buying criteria was finding the loudest alarm possible... I seem to be a heavy sleeper.

I'd actually like to put in something a little higher end, but I kind of need the alarm function. So, anyone know of a semi decent receiver with an alarm in it? Alternatively, anyone know of an alarm that will output a major nasty heartattack kind of noise through a standard line-out?
