You can get something in a pinch at Lecuit, but the prices will make you change your mind real quick...plus they usually are out of stock and have to order everything.
To get something real fast do the following:
- order at nordfoto.de (#1 for speed - unbelievable) or fotoimpex (also very fast)
- pay by credit card or bank transfer - if you do a bank transfer, make sure your bank does not play with your money for a day or two, but sends it right away (Euro transfers happen somewhere around 10 am)
-get your stuff on the morning of the second day
The expensive option: take a 2 hour train and go to Brussels to Photo Guy - has everything, in stock.
