[Ti] OT - Image bank

[Alexandre Kapellos]

Hi,
I would like to buy an image tank, a hard drive onto which I can 
download my photos from my camera, without having to take my PB with 
me... Over here in Switzerland, these thing can get quite expensive, 
around 380/400 euros/$ for a 20GB model.
I have 2 questions...
-Does anybody on this list have a particular brand they would recommend?
-My best friend will be visiting NYC in may, can any point out a good 
store in Manhattan with competitive prices that sell these things?

Thanks for any info,
Alexandre
