Well, you could buy a flat bed scanner that will also scan negatives or slides or you could buy a dedicated film scanner. Minolta has a new film scanner for $299 list. You could get a decent flat bed for $150 - $200 but the scan quality won't be as good. Here's a link to a review of the Minolta DiMage Scan Dual III. I don't have one yet but plan to buy one in the next month or so.

You could then burn the files to a cd or dvd, with the appropriate burner of course. You may also want to invest in some image management software such as ThumbsPlus, ACDSee, Jasc After Shot, Ulead Photo Explorer or Adobe Photoshop Album to help keep track of all your images and build slideshows. I like ACDSee myself. It's a powerful, full featured program that I haven't had a bit of trouble with and is reasonably priced. Most of the manufacturers have free trials that you can download and try.
Which ever route you go will be time consuming. Unless you have someone do it for you and that will be expensive. Much more so than buying the equipment and doing it yourself. With either type of scanner you will have a fixture that you load four or five slides into and then scan. You can buy another of the fixtures so you could have another loaded and ready to go when the first scans are done. It's just a matter of opening the holder and dropping in your mounted slides or negative strips, closing it and then placing in the scanner but it will be a slow process. With the Minolta scanner you'll also want to install a USB 2.0 card in your comp to speed up the scan process. It will work with USB 1.1 but will be slower.
The Minolta comes with software to help with color correction or faded images as well as software to help remove dust from the scanned images.
