I will purchase a Nikon D300 and have been quoted $1700-1800 locally. I checked out internet options at epinions.com and was led to SonicCameras for a price of $939! Called them as flags go up even for a grey market price. The saleman said 2 were in stock and the reason they could offer the cheaper $939 price was because it was made of polycarbonate plastic rather than the good US quality D300 which they do have at $1600 in stock. I asked for more details and suddenly they didn't have any in stock and it would take 8 weeks to get one. Then he found 1 in stock, 'do I want to order?' I asked what state they are in and the line went dead. http://soniccameras.com/catalog/product_info.php?products_id=4547 What gives here? Plastic Nikon D300 ?
