Daytona SS - contemplating new purchase from AD

[cheapbrass]

I was just at CDPeacock (AD in Chicago area) and after seeing a Stainless Steal Black Daytona (which they were holding for someone else who had already paid), put my name down on the wait-list for the next available one.

The saleslady told me that I might be able to get it around thanksgiving or by the end of the year, but I wouldn't really have any choice as to the color (white or black) since they are so hard to find. Just wanted to get some thoughts on the following:

1) Which is more rare? white or black? i think i prefer white.
2) The price she sold it to me for (I gave her my credit card number to charge as soon as the store gets the next batch in) was $10,400, which is MSRP. Is that a good price? since its MSRP. or should i try to find a used SS Daytona thats 1 or 2 years old? how much would those go for?
3) I noticed that on ebay brand new ones are going for about $11,500. so would i be walking out the door of the AD about $1,000 richer just by buying it?

BTW, this would be my first Rolex purchase (altho I have an old 1960s datejust that my dad gave me).

Thanks!
