I recently retired my Photosmart as well, in favor of the Minolta Scan Dual... Needless to say, I am VERY impressed with this scanner, especially for the money. I was originally going to get a Polaroid Sprintscan 35, but I couldn't justify spending the extra $$$ for it.
There are of course much better scanners out there for under $1k, but I don't know how much money you want to spend.
If you can afford it, go with the Nikon (the supplied software is awesome), if not, go with the Minolta... Then you will have an extra $400 to put towards that backup body.
To most people, the sky is the limit. To those who love aviation, the sky is home
