Here are some choices - send the slides in to a lab and get then scanned to
PhotoCD, which is very high quality, or Picture CD, which will be more than
adequate for good 5x7 prints. My guess by shopping around you can get your
slides done for abut 100 US dollars, and picture CD's for 1/3 that price.
If you want to scan the slides yourself, keep in mind that you'll spend
several minutes per slide, on dusting and scanning. For 202 slides that's
about 10 hours of work that will get old fast. Scanning is boring and most
of us would prefer to spend that time on printing and otherwise getting our
images ready for others to see.
If you want to go the scanner route, consider getting a used scanner on
eBay, scanning your slides, then reselling the scanner for about what you
paid for it. An older scanner such as a Nikon Ls20 or 30 will do a good job
and probably cost about $150. Or buy a new scanner and sell it on eBay.
But keep in mind if your price differential hits 100 dollars, you have paid
money for the privilege of spending 10 hours scanning your slides, and
getting results that are not quite as good as what you'd get by just sending
the slides to be scanned commercially.
There is the advantage that you'll be able to scan film in the future,
including any legacy images you have lying around, but why not use to the
money you'd spend on a scanner to go digital and forget about film? BTW -
using macro mode to photograph your slides digitally would also produce
adequate 5x7 images.
