Advice on your suspected degrading first: store the material properly and it is are more durable than any digital version you create today (the life-time of a harddisk is lower than the life-time of a negative). The only negative effect is that you won't be able to review them today on your PC. On the plus side - you can store them dry, cool and dark for years until you can afford to have them scanned.
Assumption second: I can only talk about scanning 135er film (24x36mm pictures, german "Kleinbild). I literally have to take digital pictures of the few rolls of 120er film (6x6 cm) I shot in my childhood.
I own an Nikon Coolscan V ED for scanning 135er-film. Works nice with stripes of ~5 pictures, as it has a feeder-unit. I use it mainly for my own pictures, as I shot analogue SLR until last year, but today I'm roughly in the same position as you - my father shot a lot of reversal film for projection (and I remember fondly glueing glass plates with the pictures together with him). There is no feeder for framed pictures for the Nikon V. But there is one for the Nikon 5000. Two warnings:
- these scanners are not cheap (also, because they are not really sold anymore)
- choose the cheap and it costs you more time / effort (been there ...)
- the software (be it Vuescan or Silverfast or ...) costs too
- it takes (a lot of) time
- to find the right settings (DPI, colour-curves (!))
- to scan and store (with stripes, one starts the batch and ignores the program for 20 minutes (multi-scan))
- to sort and post-process, if you are into quality
If you still want to scan on your own, I bought mine four years ago from http://www.filmscanner.info/en/ - they have some nice reviews ... and a scanning service too ;)
PS: reminds me of the Vivan Maier - article (http://vivianmaier.blogspot.com/) about the young guy discovering an amazing street-photographer from Chicago. Don't know which question here linked to her.
