Buy.com may have the best price currently for the new 505, both silver and blue, if you can wait for them to get restocked. Their regular price is $277.99 with free shipping and no sales tax. There's a 5% discount coupon available (
http://www.buy.com/retail/coupon.asp?prid=84773074) that brings the total down to $264.09. I've done business with them a number of times and they're legit but I have no idea how soon you'd get one if you ordered now.
I'm new to the Forum although I've been reading it for several weeks as I wait for my new 505 on 11/7 - my birthday (I'll be 61). Birthdays are still exciting!
