I know all about the 'net being a medical must have.
I have a step-grandson with a terminal illness and we use the 'net extensively for his needs and all the other kids that suffer the same problem.
So 'net access is a top priority here at home.
I do support SubSim with donations along with a couple other forums as I can.
Not for what I can download but for the people that I have become friends with through the forums.
Take a day (or 3 or 4) and find all the freeware from other sources.
It's out there.
Good hunting.
