I used an Epson Perfection 1650 to scan in about 4500 35mm colour slides and
the results were very acceptable, I can send you an example if you wish.
The drawback was the length of time involved, it is a slow process with such
a scanner and I would not like to do it again.

This is a topic about once a month in this group and over in the
digital one.  Please seach back threads and you will get tons of info.
If can't go it though your newgroup company, use Google groups.

In a nutshell, here's what you will find.  There are a lot of high
opinionated views on this.  Personally, I think that no one is right
and no one is wrong.  It is just a matter of taste.

You major options are:
1.  Flat bed scanner:  Pros:  quick, cheap and you have one.  Cons: can
bet better quality other ways.

2.  Dedicated slide/negative scanner:  Pros:  great results and some
scanners are reasonable.  Drum scanners are superb, but very expensive.
Cons:  Slow.

3.  Adaptor for dSLR:  Pros:  Cheap and quick.  Cons:  Resolution
limited to your camera's resolution, lighting can be tricky, some
lenses are the best.

In all cases, probably 90% of the results depends on how good the
operator is and your willingness to make corrections after the scan.

Good luck with it and check back threads.  If you have any questions
after you've read that, be sure to post them.  There are some pretty
knowledgeable people you there.
