Hi rubberman! Thanks for your thoughts!
I have actually identified a number of systems -- gaming machines, mostly -- on Amazon or Newegg that meet all my requirements in the $1300 range. And I have found a few that almost meet them in the $7-800 range. Plus my current computer is six years old, and it is time to replace it. The question is, can I get the price down to the $1000 level for which I was hoping.
Whether I can or not, I'll take another look at Amazon. But I think it is unwieldy to be uploading a 16 gig file from my home every time I want to do work. It's not like I have a T2 line.
Warmest regards, Andrew
