I'm basically repeating what alexh said.
$2.82 at dealextreme with free shippingI had a 40 gigger in my A600 earlier, but experienced too many problems trying to exceed the 4 gig barrier. So, instead of using just 10% of the drive, I replaced it with the said adapter and a 1 gig CF card.
On the Amiga, 1 gig is quite a lot.
