Last December there was a very timely and interesting discussion about slide scanners. I too have been interested in scanning my many slides and have been waiting for the prices of some of the better Nikon units to come down. The Coolscan 4000 looked very interesting but it looks like it has been discontinued and replaced by the 5000. Has anyone seen any reviews of this new unit? It is USB 2 instead of firewire. Don't know if that matters as most new Macs have USB. On a similar note, does anyone have any experience with the automatic slide feeders. I had heard the one for the 4000 had occasional jamming problems. Maybe an automatic slide feeder is overkill. Comments? Thanks everyone for all the good info. Mike
