Digital BW, The Print

Hope this isn't too far OT.  Though most of my stuff is digital capture now,
I have a large backlog of 120, 4x5 and 8x10 b&w negs to scan.  So far I have
been using a Heidelberg (Linotype-Hell)
Saphir Ultra 2 SCSI I bought in 1997 or 1998 (about 200 years ago in human
years).  I see the Epson 4990 Pro also takes up to 8x10 negs, and purports
to have a range of 4.0 and 4800 ppi optical.  I would appreciate it much if
anyone on the list could comment on whether that would be a meaningful
upgrade from my old Heidelberg, or point me to a resource.  If it is really
true that it has 4800 ppi optical, that would be a pretty large scan from
even 120 film.  (I can't afford an Imacon).  Thx!
