What is an affordable, versatile scanner for negatives and prints?

While I'm aware, from reading some earlier threads on scanners
in these groups, that this is a "semi-dumb" question, I haven't quite
found the answer I'm looking for.
I am looking for a scanner that can do 120 and 220 medium format film,
as well as 35, and can handle prints, too. I do not need "professional"
quality, but I would like at least good enough that the results aren't
offensive to the eye (as many low end scanners are).
Now, in most electronic gadgets, there seems to be a range of products.
There is the very best, which gets the best results possible, functions
at the highest level, and is insanely expensive. Then there is pure junk,
which gets crappy results, works poorly, and is cheap as dirt.
I'm looking for something that gets good results, may have some quirky
behaviors or other inconveniences, and is at the lower end of reasonably
priced (or has been around long enough that used items are pretty easy
to find). I'd basically like something that isn't going to lose a tremendous
amount of quality in the scan, produces results that can be turned into
something reasonably presentable in Photoshop or other software, and
isn't insanely difficult to use.
So, to put it another way, if you were not recommending a product for your
technically illiterate grandmother, but instead, were recommending a product
for your somewhat cheap brother-in-law, who had a medium format TLR camera
and a 35mm SLR camera, and wanted to do a couple dozen scans a month,
what would you recommend?
