I've been retired for eight years now. I still don't like slow, 
repetitive tasks. And I don't see how I ever found time for work. :-)

Ouch! I've been luckier. The stuff I scanned with the FS2720 at 2700dpi 
still exists as the original TIFF output files, before post processing. 
So unless I want higher resolution for a frame here or there some day, 
which has happened a very few times, I don't have to rescan.

The 4000 ED and FS4000 are different designs, nominally the same 
resolution, and I think pretty much the same in practical results. 
However, I don't think Epson reached the true resolution and IQ level of 
the Canon 9950F with their 4850, or even the 4990. Only with the 
V700/750 did they reach the full potential of flatbed 4800dpi, just 
edging out the 9950F

Neither do I, if I can really see a difference.

That's why I scanned some frames with both FS4000 and 9950F, did the 
best I could with scanning and processing, then compared them. The 
difference in detail resolution is really tiny. I can only see it pixel 
peeping at 100%, flipping from one to the other as layers. I just don't 
think I would ever see it in even a really large print.
