Digital BW, The Print

Hi all,

Can any of you recommend a scanner for (old and delicate) 4x5 negs? It's not for me, but 
for a friend who is considering purchasing a pro-sumer oriented model and hiring 
someone who knows what they're doing to use it, with the end result being poster sized 
prints.

 I think his price range is up to around 5-ish grand.

If this topic has been beaten to death, could someone direct me to an archived thread? I 
haven't found anything specific yet.

thanks!
Sarah
