Hi,
I had the same problem, wanted a Sony but had troubles finding a reasonably-priced seller...
I found
Advanced MP3 Players - it's located in UK, but
they ship internationally -just received my 505 an hour ago ;D (can't wait 'til it's all charged up and I can start playing with it!)
I placed my order on June 27th, both the reader and AC-charger were out of stock then, but they kept mailing me updates on my order ("we are expecting stock on July Xth", "your order is being picked and packed", and of course the most important one: "your order is shipped" with a tracking code). The package was shipped on Wed, and it got to Finland in two days with FedEx.
I even managed to find a coupon code for the company: "jolly" - 10% off the price
