Horses for courses, Jhieminga, I'm here for a good time, not a long time!
I've done 1000, got 2000 to go, a fair number of those pretty faded.
Scangear lets you preview most of the adjustments you mentioned as well. I rarely use them; perhaps a bit of a saturation boost. Another plus is you can do 3 pics (4 of those little 3½" x 5") at once.
600DPI Jpeg looks fine on my big TV = good enough for me.
