Thanks everyone for the warm welcome and great advice.
@ Joe Co, I normally wouldn't mind buying pre-owned, especially if it's at a significant savings. But since it's to commemorate my 40th, I thought I'd splurge and get it brand new, and hold onto it for a long time.
@ Julius, great advice on buying from boutique if paying MSRP. I'll check out the ADs first for discounts. If no discount, then I'll head down to the Beverly Hills boutique. I have a couple of buddies who live in the LA area whom I can visit while I'm down there. But I'm not sure I can make it down there before 9/12.
