slide scanning: what do you use?

Anyone out there digitizing slides? I'm interesting in buying something that will do at least 20X (preferably 40X) without spending $30,000. There are plenty of pricey whole-slide imaging "systems" out there, but surely there are some desktop film scanners that are up to the task? How about the Nikon Coolscan units?
