I have a Noblex and have been scanning in transparencies with an
Epson 1600. The nominal resolution is 1600 dpi so if you assume
you want about 300 dpi sent to a printer then you can get 5 to 6x.
Giving 6 inch high prints.
Apparently the scanner will do 3200 in one dimension so if you don't
mind interpolation you could get 10 or 11 inch high prints.
So far they look pretty good to me, the prints are not as sharp.....

I have both Roundshot 35/35S and Noblex, so I was looking for a 
scanner that will accomodate both.

I saw that the Epson 1600 was spec'd at 1600 dpi (when a spec says 1600
X 3200, forget the higher number -- it refers to mechanical stepping
in one direction only) I thought it would meet my needs and I ordered
one.

The first arrived defective.  The second, while it worked OK, did
not give me the sharpness I expected (I want it REAL SHARP!) on
4 inch tall Roundshot images and 8 inch tall Noblex images.
 
I made some comparison scans made using the PowerLook III and
Saphir Ultra 2, both 1200 dpi scanners.  Based on this, I've concluded
that the "real" resolution of the Epson is only about 1200 dpi -- not
enough to keep me happy.  Back it went!!

I'm now looking at more expensive scanners -- I've made comparison
scans on the same negatives used in my earlier tests using the Agfa
T2500 scanner, a 2500 dpi unit, and they are MUCH better.  I've not decide if
that unit is worth $4300 however.  Microtech will soon be
offering the same unit under their brand name & I'm waiting to see
it's price.
