Photoworks out of Seattle will scan and put them on disk for you at a very reasonable cost. I had hundreds of slides converted in groups of 20 done for about $8 per group. The groups could be higher now, when I had them do it, 3 1/2 floppy was the only thing around, no CDR's yet. They also did old, really old family photo's too.
The quality of the conversions was excellent, crisp on a 21" monitor.
One problem with them, all the pics came back in their own file format, .swf IIRC, but their program (free) came with a conversion to .jpg program, pia to convert all of them, but it worked. That could have changed too, maybe now you can get them back in .jpg.
They're still around
