Anyone have any feedback on Nikon Coolscan 5000 versus the Pacific Image Powerslide 3650 I have a large pro library to scan and may need to do batch scans. I realise the Nikon is highly rated but its very expensive if you add a feeder unit. I mean how good is the Pacific anyhow? I have to hi-res scan the hero images before they fade or get fungus etc Not fussed how long it takes. Any feedback welcome.
