Looking at the scanner comparison on this site

http://largeformatphotography.info/scan-comparison/

I'm impressed by the performance of the MicroTek ArtixScan 2500f. Checking their site, it was introduced in 2002, and it doesn't look like it's sold any longer.

How does the 2500f compare with MicroTek's currently offered 1800f for scanning film?

While I've gotten some nice images with my relatively inexpensive Epson 4870, it's kind of dismal comparing it with some of the other scanners. But for the price, what can one expect, I suppose.
