(1) As far as I know, in-dash CD players are all of the
	insert-disk-through-the-slot variety.  I hesitate
	to purchase on of these since i fear the CD is
	vulnerable to scratching as it is pushed through
	the flap on the slot.  I am hoping that someone
	out there can put to rest these fears so that I
	can listen to crystal clear high fidelity in my
	soon-to-be-purchased-to-go-with-the-CDplayer car.

(2) I understand that, when playing a VERY scratched disk,
	the single beam CD players put out less noise and
	fewer errors than three beam players.  

	    I was given a demonstration to this fact(?) at
	a stereo shop: the salesperson brought forth a
	store demo disk with a significant amount of 
	scratches from being thrown across the salesfloor
	(to demonstrate it's durability to previous
	customers) and stepped on.
	    
	    He played it on a brand-x three beam machine
	and the noise and errors where definately audible.
	He then proceeded to give the disk a run on a
	single beam Sony (he said all Sony machines are 
	single beam due to this advantage) and the noise
	was either inaudible or significantly less than
	the aforementioned three beam machine.  
	    
	    Any comments on why this is so, IF this is so at
	all?
