Welcome aboard....
I ran a Nexpress for 2 years and now the Igen for 2 years and I can tell you that the Igen is a much better machine for lots of reasons. I would also like to add that since Kodak took over the Nexpress they have made some nice strides so those reasons are getting less but because of the layout of the machine I think it will always have some down falls.
Some of the things that separate the Igen from the Nexpress are:
The ability to print nice solid blacks...
The ability to print on very textured stocks..
The ability to Roll feed.. Inline UV Coat... (I know the Nexpress glosser, but it is toner)
More up times and quicker daily maintnance....
Flexability to add stackers/Feeders.....
Speed...
etc.
Don't be fooled by the complaints you see here. This site is to discuss problems so you will see more problems posted than success stories. But all machines have their share of problems, and some might just be operator related, so take it with a grain and know tha the Igen is a good solid machine as you will soon see..
