In reply to David Coley: I use an Epson V700, which does a pretty good job.
The main advantage is that the slide carrier can take 12 slides at at time, anything less is a nightmare of perpetual changing of bits.
I haven't found the digital ice software much good other than for massively increasing file sizes and slowing scanning times, tbh, if you have a particularly good picture you will probably get better results from photoshop or paintshop pro. Beyond a certain resolution, it is very hard to see that there is any gain.
It remains a SLOW process!
