You can steer clear of Epson, but what were you expecting for a $200 film scanner?
I scanned close to 5,000 images with the 2450, then realized upon seeing what Nikons were giving that I'd asked too much of the 2450 on 35mm slides -- which I think was $500-ish 17 years ago. I begrudgingly (!) re-scanned every slide, but the 4x5 scans were and are still very usable.
The V750M-Pro "wet mount" scanner I replaced it with just for 4x5 film scans blew the doors off anything any lab had ever done for me. I recently made a 90x90 trade show print from one.
I've never had an issue with either, but as we know Luck can be a cruel and indecisive beast.
Scanning has been a part of my daily routine for the past two years.
I am now approaching 40k slides/negs (35mm) scanned using an Epson V850 and Silverfast software. It is not perfect, but I sell the scans and get them published in books and magazines.
For the New Year I am probably going to change my method and use a camera instead.............this has become the industry standard, LAT has five people working through their massive archive utilising this method, most of the big museums are also doing things this way.
There is a wealth of information and a book to be found HERE from pioneer, Peter Krogh.
I suspect there will be whole new learning curve heading at full tilt towards me in January.
